my tests I measured about 2% slowdown.

shown and 0.5s hidden (instead of 1s each). Tell me what you think.

an alpha channel of itself, we have to respect B_TRANSPARENT_MAGIC_* pixels
and properly make them transparent. We achive that now by just setting the
alpha to 0 in our converted B_RGBA32 bitmap for each pixel where there is a
B_TRANSPARENT_MAGIC_* pixel in the source. This is not really efficient, but
fixes missing images for example in NetPositive. They were treated as B_RGBA32
while they in fact were B_RGB32 and happened to have all alpha bits set to 0.

the front buffer, draw the bitmap, restore the copy to front buffer state and
unlock. This fixes that the updated button state was not actually copyied to
the front buffer (and therefore visible) when a window was inside an update
(disabling front buffer copying).

need to be drawn each time an update occurs (switching focus/non-focus or
pressed state, involving many graphics card blits and state updates in the
drawing subsystem).
* Provide a shared list of already present bitmaps. All the default decorators
now use the new _GetBitmapForButton static method to get a rendered bitmap
of the button for the given size and state (focus, pressed). If a matching
bitmap exists it is returned, otherwise a new one is created on demand using
a shared BitmapDrawingEngine.
* Cache the colors of the tab and frame for both focus and non-focus states to
avoid always looking them up.
* Added a todo that these bitmaps and the BitmapDrawingEngine are never freed.
They should be freed on app_server quit, but as there are only like 12 of
them anyway I didn't really bother.
* Some cleanup.
This should reduce the waste of cycles for just drawing the default decorator
buttons quite a bit. Probably the whole tab should be pre-rendered though to
also safe the text rendering of the title.

server side UtilityBitmap of a certain size. It sets up the DrawingEngine, the
UtilityBitmap and the BitmapHWInterface necessary so that one can directly
do drawing to a bitmap using the normal DrawingEngine interface. It provides
an ExportToBitmap method that allocates an output UtilityBitmap of a specified
size and color space where the content is put into, so a single instance of a
BitmapDrawingEngine can be reused for various drawing.

InvalidateLayout().
This fixes#1461, the bug appeared because DraggableContainerIcon uses a special trick, involving changing the resizing
mode, to get the total width of the menu items. (see tracker/ContainerWindow.cpp line 479)

We now keep track of a lower bound as to when the list should scale
itself back down. When increasing the list size, we double the current,
with the lower bound set to 1/4 of the current size, not allowing it to
go any smaller than the block size. These combined allow us to do very
cheap tests to see if an operation requires a resize at all, and minimize
how often the list actually needs to be resized, since the difference in upper
and lower bounds prevents bouncing back and forth between a size in the case
of adding/removing an item while close to a boundary. All in all this should
make BList noticably more scalable when doing large numbers of add/remove
operations.

When changing to icon mode with a size other than 32 (ie: kScaleIconMode) PoseView calls Refresh() and all the poses are
removed and loaded again (PoseView.cpp line 1995). This called AddPoses but didn't check for ShowDiskIcon(). The Disks icon
was shown on startup though, since Tracker uses another code path when starting (caching?).
This fixes#1833.

state of the painter without restoring it afterwards (HighColor and
DrawingMode).
This function is only used in decorators, but as such it could lead to
strange effects. When clicking and holding the close button on the R5
MidiPlayer for example, the background of the scope would suddenly become
the color of the close buttons middle line. As the drawing mode was also
overwritten this could probably have lead to text rendering issues when
zooming applications. As I didn't find a easy way to reproduce such a thing,
this is only theory though.
* Implement the missing IsExclusiveAccessLocked() method in the DrawingEngine
which is not used at the moment. If corresponding debug output is generated
though, it reveals possible locking issues with CopyRegion().
* Remove an empty line in the LineArrayData struct.

the delta.
For example, MoveBy(-0.5, 0.0) would do nothing in this case:
roundf(150.0 - 0.5) = 150.0, when rounding the delta it gives the
expected value: roundf(150.0 + roundf(-0.5)) = 149.
On the other hand, BView::ResizeBy was doing it right, and this
explains the bug in Cortex (#333). Cortex was doing
scrollBar->MoveBy(-0.5,0) then scrollBar->ResizeBy(0.5,0) and the
inconsistency lead to the visual bug. (see StatusView::MouseMoved())
This fixes#333. The bug was strange to reproduce since sometimes the
point received in MouseMoved would be "some_integer+0.5" values
sometimes just integral. This has still to be investigated though not
problematic here anymore. See cortex/RouteApp/StatusView.cpp line 222.

BIOS owned flag and clear all possibly enabled SMIs. It seems to be common
practice to just ignore this error case, probably because there are enough
broken BIOSs out there that do not correctly hand over the controller.

BasicTerminalBuffer. It synchronizes this buffer with the actual
terminal buffer and uses it for drawing. This does significantly
decrease the time the terminal buffer is locked by the window thread,
and avoids the necessity to do invalidations in Draw() when the
terminal buffer changed in the meantime.
* When the view detects heavy scrolling of the terminal buffer due to
lots of continued output, it throttles redraws to one every 0.1s. The
detection condition might need some fine-tuning -- it's probably a bit
too strict for most situations.
I guess I'm done now with optimizations. After testing on real iron for
the first time, I'm a little impressed. In the "time seq ..." speed
competition Haiku's Terminal easily beats Konsole by 10 to 20% for 80x25
and by factor 3+ for full screen. And if I interpret the results
correctly 90% of the time is actually used by "seq" itself which seems
to be about 5 times slower than under Linux.

we now double/halve the current size of the list, starting with the constructor blocksize as a baseline.
This has the net effect that when doing large numbers of inserts/removes, the number of resize operations
needed scales logarithmically to the number of operations, which should yield a decent performance
improvement in such cases.
Review welcome. This does not yet affect ticket #2363 that I'm aware of, as I'm currently in the process
of attempting to find a copy of said app to test with.

handover indeed worked. Doesn't really matter though, as we reset anyway,
just not twice in the success case.
* Disable all interrupts and clear any pending active interrupts just after
taking over the controller. This might fix bug #2361.

the same time.
* Added a SynchronizeWith() method that allows synchronizing with (a

whole screen.

* Introduced a small (64 byte) buffer for the parser thread. Instead of
directly reading single characters out of the reader buffer, we read
a full parser buffer and process the characters from the parser
buffer. Thus _NextParseChar() could be inlined, since it merely
consists of a conditional method call and an access to the parser
buffer, now.
* Improved the locking of the terminal buffer. Instead of unlocking and
relocking after every multi-byte char or escape sequence, we only
unlock while refilling the parser buffer.
