59e13a3f06 Patch by Andrej Spielmann (GSoC):
* Simplified the subpixel related methods for the AGG "pixel format" template
  interface, the ones for the solid cover simply pass through the existing
  methods, so only one subpixel blending function is left which does the actual
  work (this removes a lot of the previously added code)
* Implemented a new rasterizer based on the original AGG rasterizer which
  implements subpixel anti-aliasing for any generic AGG vector pipelines. It
  is now optionally used in Painter and AGGTextRenderer (for vector fonts, ie
  rotated, sheared or big enough fonts) depending on the global subpixel
  setting.
* Put all subpixel variables into the new GlobalSubpixelSettings.h|cpp
* Simplified DesktopSettings related classes a bit and renamed previous
  FontSubpixelAntialiasing to just SubpixelAntialiasing.
* The private libbe functions for subpixel related settings moved from Font.cpp
  to InterfaceDefs.cpp where other such functions live. They are not related
  to fonts only anymore.
* Removed the subpixel related settings again from the Fonts preflet and added
  them to the Appearance preflet instead.

All of the above implements subpixel anti-aliasing on a global scale, which
to my knowledge no other OS is doing at the moment. Any vector rendering
can optionally use subpixel anti-aliasing in Haiku now. The bitmap cached fonts
are still affected by the Freetype complile time #define to enable the patented
subpixel rasterization (three times wide glyphs). Vector fonts and shapes are
not affected though at the moment.

cc6c784ae7 * Sean C. Farley made me aware that some of the possible solutions to clear
the environment would crash on Haiku. Added a small test application that
  just checks every one of those.
* Fixed env locking (in userland, you better check against B_INTERRUPTED).
* Made our code safe against an environ of NULL.
* There is now an additional sManagedEnviron that points to the environment
  our code actually managed; whenever an application overrides environ, we'll
  get aware of it with the next *env() function invocation, and will handle
  it adequately.
* Added non-POSIX clearenv() function.

7f12cc54a7 * It is now supported that I/O operations and requests are only handled
partially (e.g. due to hitting the end of file). The respective
  classes have grown new methods and attributes to deal with that. The
  "finished" callbacks have got additional parameters to indicate
  whether the transfer was only partial and how much has been
  transferred. Other callbacks and functions have a size_t* in/out
  parameter instead of a simple size_t, now.
* vfs_{read,write}_pages() do now use the I/O request framework instead
  of the underlying FS's {read,write}_pages() hooks (those should be
  unused now). Furthermore they've got an additional "flags" parameter,
  which is passed to IORequest::Init(), i.e. it allows to specify that
  the given vecs refer to physical addresses.
* The file cache's read_into_cache() reads directly into physical
  pages, now.
* Fixed bug in DoIO::IO(): The offset was not adjusted, so that all
  pages were incorrectly transferred from/to the same location.
* Fixed broken subrequest scheduling loop head in
  do_iterative_fd_io_iterate().
* Adjusted the test driver and implemented its io() hook. Using this
  driver I/O requests are passed all the way from the VFS/VM to the
  driver and through the I/O scheduler. It even seems to work. :-)
* Added missing const to the iovec* parameter of the IORequest::Init()
  methods.
* Disabled some debug output by default. Added new optional debug
  output.

b4e9c99bc4 * Added a SetupClipping() method to Test baseclass, which adds about 400
small clipping holes to the TestView user clipping.
* Added a bunch of new tests. Here are some numbers from the test environment,
  which is similar to running Haiku in VESA mode:

Horizontal lines per second:
Haiku:	192964.663	(117,7%)
ZETA:	163977.006

Vertical lines per second:
Haiku:	 90109.985	(276.9%)
ZETA:	 32538.458

Random lines per second:
Haiku:	  7998.451	(23.1%)
ZETA:	 34602.539

Random colored lines per second:
Haiku:	  7976.437	(22.9%)
ZETA:	 34788.247

Random clipped lines per second:
Haiku:	   262.180	(2.5%)
ZETA:	 10394.794

Clipped glyphs per second:
Haiku:	  5911.526	(1.0%)
ZETA:	590508.726

Obviously the clipping performance is a punch in the stomache.

7c2658585f The start of a benchmark application to test various performance questions
of the Haiku app_server. The immediate comparison are of course BeOS and ZETA.
Currently, it measures the performance of drawing untransformed text. For
now, I have only tested on ZETA and the app_server testing environment. Will
let you know my findings with Haiku running on real hardware.

c1cec366af * Removed B_USER_IO_REQUEST flag. It was superfluous, since whether the
buffer lives in userland can easily be checked via IS_USER_ADDRESS.
* Added B_VIP_IO_REQUEST flag which will be used by the page writer and
  should cause allocations to be made in a way that they cannot fail.
  Not implemented yet, though.

91ccfa19a0 Added missing vm_put_physical_page() in do_io().
Something is still fishy though: Opening the dma_resources_test device
in DiskProbe, the wrong data is shown. do_io() seems to be invoked with
the correct physical address, vm_get_physical_page() succeeds, and after
memcpy() the correct data are in the virtual address it returned, but
db in the kernel debugger shows that the data in the physical page have
not been changed. When quitting DiskProbe the "page still has mappings"
assert is triggered for the page.

8faff60c7f * Enabled all DMA tests, wrote some more.
* Moved data buffer creation to a TestSuiteContext class.
* Added checks if the I/O operation does the correct thing, ie. reads/writes
  the data to the right offset.
* Rearranged DMA translation: we now handle the partial write case correctly
  (bounce buffer must always span over the whole block), and are able to join
  adjacent bounce buffers together.
* The new _AddBounceBuffer() method also respects boundary and segment size
  restrictions for bounce buffers.
* IOOperation now prepares the outgoing vecs/offset/length to contain the
  right data for the current phase (partial read begin/end/do-all); it will
  also make sure that the lengths of the vecs are of the same size than the
  whole request.
* All tests are now passed, the I/O request implementation seems to be ready
  for integration now.

45a206a742 axeld + bonefish:
More work on the I/O scheduler, more precisely mainly the DMAResource class:
* When splitting requests into operations, we're now able to flexibly mix
  bounce buffer segments and the given physical vectors in a single
  operation. This reduces the number of operations.
* Squashed several TODO and fleshed out more of the implementation.
* Added a test driver running unit tests. There are only a few tests yet,
  but those pass.

3d75dfbb4a Adding a DrawingModes test application that uses the different drawing modes
to draw a bitmap and a B_MIXED_COLORS pattern. This shows that most of the
Haiku drawing modes are off of what the BeBook documents them to be and also
shows that B_OP_SELECT is actually broken under R5.

3c905d812f Adding DrawingDebugger app that creates a port listening for BRects that then
get drawn into a window with random colors. With that one can for example add
code to the app_server or interface kit classes that push through rects or
regions to see what exactly is going on in drawing operations. Code examples
of how to use are at the top of the file. Has fixed window dimensions though
as I was lazy :-)

680a35bbdb Add a simple test that demonstrates that the Haiku app_server incorrectly
(or at least incompatibly) uses the user set clipping region when determining
whether or not to call Draw() on a view. Under BeOS when a some part of a view
is exposed it will always trigger a Draw(), even if the current clipping region
disallows drawing in the supplied update rect. Under Haiku however the view is
not considered for an update when the current clipping region does not
intersect with the newly exposed area.
Running this test app from the Terminal this behaviour can be seen. When
clicking inside the window a floating window pops up. When clicking again it
goes away and triggers a redraw. When hitting a key, a clipping region is set
that does not overlap with the floating window. After this clipping is set,
the view does not get any Draw() call anymore when the floating window goes
away.
This is the reason for the redraw issues in firefox, as firefox uses the
clipping region to constrain its asynchronous drawing, but does never reset
the clipping to NULL. As firefox just collects the update rects in Draw() and
then draws the contents itself, once the clipping region is set, many of the
Draw() calls don't get called and the interface parts are never redrawn.

b30304acc8 * Add a DumpFontList test that dumps all families and styles with most BFont
infos (should all be defaults expect for a few).

This shows that with our default installation there are quite a few "condensed"
styles and also an "extra light" variation. The condensed ones should probably
get their own face flag. The "extra light" and other unhandled styles should
probably not be classified as a B_REGULAR_FACE as this could lead applications
to use them in a wrong way yielding unexpected results (i.e. firefox that
picks up the "extra light" style for it's interface font).

9f925127db This should be the last commit to this one, I'll next work on integrating it
into the kernel:
* Added device_removed() function to the device level as well.
* A device_node now also tracks its published devices.
* Made the driver API more consistent with the device API; instead of the node,
  they now get the driverCookie (so they now need to store the node themselves,
  the driver cookie could be retrieved via the node).
  Alternatively, one could either pass both, or have something similar to what
  Ingo did for the file systems, ie. pass a structure that contains both
  elements. Suggestions welcome.
* Implemented device node replacement when a better driver becomes available:
  the new node (and its devices) is already published even though the old device
  is still in use. The new device is B_BUSY until the old one is closed.
* Implemented an update cycle counter: this will prevent a device node from
  being probed again, if there is no new driver since the last time; eventually
  this will be moved into devfs, though.
* Driver removal and replacement now works as expected in all tested scenarios
  (device removed, better driver installed, both with and without open device).

* added a very basic devfs emulation to the playground to be able to test how
  the manager reacts to opened devices.
* renamed *_device() functions to *_node() in the device manager API.
* made B_DEVICE_FIND_CHILD_FLAGS a generic flags field, and renamed it to
  B_DEVICE_FLAGS.
* added support for keeping a driver loaded as long as its device is available.
* implemented get_next_child_node().
* added test for device removal, and implemented unregister_node() for this.
* fixed some bugs in the device node reference/initialization count maintenance.
* moved more code from register_node() to device_node::Register().
* initialize the device_node::fFlags member to the value of B_DEVICE_FLAGS, and
  have additional private flags.
* renamed UninitUnusedChildren() to UninitUnusedDriver(), and fixed this
  function by adding the new flag NODE_FLAG_REGISTER_INITIALIZED.
* Now remembers the support when a driver is registered - this will be used
  later to be able to compare with a new driver without having to call
  supports_device() again.
* Removed NODE_FLAG_REMOVE_ON_UNINIT again, as that was pretty stupid - there
  is reference counting for a reason.

548c508ff7 More work-in-progress:
* Added a generic (for all devices) and specific (for a specific device) video
  driver to be able to play with the replace mechanism (which is not yet done,
  but works well for the one usage case tested).
* Added reference counting and initialize counting: now, each node owns a
  reference of its parent, and each initialized node owns an initialization
  reference of its parent.
* Added locking.
* Moved dump functionality into a member function.
* The same node can now only added once - ie. if a bus tries to register the
  same device twice, it will fail.

2873ace1f1 Small test program triggering a self-deadlock in the memory allocator
when a signal handler that itself uses the allocator is invoked while
the thread originally was in the allocator.

2f00291de2 * The EXIF parser now keeps a set of visited offsets to avoid entering endless
loops with corrupted data.
* This fixes bug #2206.

d5becaf83b Test for setjmp() that demonstrates why it isn't a good idea to
manipulate the stack pointer as we do.
