* We also have to keep the source file around and properly dispose it, as
OffsetFile doesn't take ownership of it.

is called after BeginPicture on a freshly created view.
This is necessary because a second invocation on this view with BeginPicture
would have caused ServerPicture::SyncState to write the default drawing state
into the picture. This happens because to BView had now cached the values and
therefor won't go to the app_server and tell about the change. The first call
did not change anything as picture recording is handled in _DispatchPictureMessage
while view changes that modify drawing state are handled in _DispatchViewMessage,
thus leading to default draw state values beeing written.
This fixes invalid ticket #2534.

a regression in MediaPlayers peak display where the last row of pixels was
wrong.
* Fixed clipping rect bugs in the new bilinear scaling loops, the last row
and/or columns don't always need special treatment, only if they map to the
last row and/or column of the destination bitmap.

nearest neighbor scaling, I noticed that the bilinear version
actually used less CPU than the generic AGG code path with nn
scaling. So I wrote an optimized nn scaling routine for nn
based on the bilinear scaling code. So the indices into the
source bitmap are cached. I don't know if this is the optimal
nn scaling routine, but the CPU usage dropped significantly.
Only B_OP_COPY is optimized as of yet.
* Optimized the bilinear scaling. When more filtered pixels than
unfiltered pixels are anticipated, the loops are unrolled to
special case the very last row/column and bottom right pixel.
This eliminates the branches in the loops.
* Fixed a bug with partial scaled drawing of bitmaps when it
used the bilinear scaling, the bitmapShift was in the wrong
direction.

lock held.
* Added a TODO comment in _ActivateApp() on how we could handle minimized
windows.
* Added a WindowList::Count() method.
* Added a WindowList::ValidateWindow() that you can use to validate a window
pointer in case you had to unlock the list.
* Made FirstWindow()/LastWindow() const.

better call Window::SetMinimized() before calling it from there.
* And since ShowWindow() calls _SendFakeMouseMoved(), we also better don't
call it with the window lock held, or otherwise we would potentially cause
a deadlock.

* 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.

before?! Is about 4% faster than before. If anyone sees a way to make it faster
yet, please shoot! I can watch movies fullscreen on a 2 GHz Core 2 Duo in
VESA with bilinear scaling, but it would be nice to use less CPU... :-)

const BBitmap* bitmap, BRect bitmapRect, BRect viewRect, uint32 options).
Only option so far is B_FILTER_BITMAP_BILINEAR.
* BView::DrawBitmap[Async](const BBitmap* bitmap, BRect viewRect) was accessing
the bitmap pointer without checking it. Would therefore crash when passing
NULL, unlike the other methods.
* The BPicture code already reserved room for the BBitmap flags, but did not
store the actual flags and neiter use them for anything. Since the bitmap
data is stored anyways, the bitmap creation flags do not matter. So I reused
this for the new bitmap drawing options.
* Rewrote Bitmap.h and removed the B_BITMAP_SCALE_BILINEAR flag again.
* Tried to optimize Painter::_DrawBitmapBilinearCopy32() a little by giving
the compiler better hints. There seems to be a marginal, possibly imagined
speed increase < 0.05 ms. ;-)

need to be interpolated because the x index is right on a source pixel. This
prevents the out of bounds access for the second to last row in the last
column. Also the rightmost pixels where incorrectly interpolated with the
leftmost pixels of the next row. And it actually helps speed too of course.
* Added a compile time option to allocate the filter weighting and index
caches on the heap instead of the cache. I am not sure if it is a problem
though, I recall Haiku threads have quite a lot of stack space. The needed
memory depends on the target size. For a screen with 1920x1200, the caches
would need 12.5 KB. Allocating them on the stack saves about 0.2 ms on my
test system.

B_OP_COPY which is about 2.4 times faster than the AGG version (but of
course less generic). The speed up is even better for smaller and even
scales.

* When drawing BBitmaps with scaling in the app_server, use a bilinear
filter when a bitmap has this flag set. (Hope nobody objects, otherwise
I can revert or improve this. Performance can certainly be improved, since
the AGG implementation is too generic. But that goes for the nearest
neighbor implementation as well.)
* Flags are uint32, fix app_server side code to declare them correctly. Use
appropriate link methods in BBitmap and ServerApp.
* Enable the BeOS compatibility mode for B_RGB32 (works just like B_RGBA32
in B_OP_ALPHA mode).

It works by adjusting the display_mode to have twice the virtual height to
cause the graphics driver to allocate enough frame buffer. Since hardware
acceleration calls are based on geometry locations instead of memory locations,
accelerated calls can work in the offscreen buffer with this method.
Similarily, the new CopyBackToFront() method copies the back buffer into the
front buffer with hardware acceleration. The code is currently disabled, since
not all graphics drivers handle the virtual versus display size correctly,
for example the intel_extreme driver. It works for example with the radeon
driver, but another problem prevents me to judge the benefit of this method.
Most types of screen redraws are flicker free, though, which is the whole point
of the excercise. :-)
Another problem with the current code is the initial mode switch. It does
not try again to double the frame buffer in the fall back code paths. It could
also check the frame buffer memory at all, before even trying to save some
cycles.
To see it in action, uncomment the code at line 508.
