is managed for those bitmaps:
- the shared client memory mechanism is used to allocate a small overlay_client_data
structure that contains the actual buffer and a semaphore that you have acquire in
order to access it.
- LockBits()/UnlockBits() now have a function: you need to call them before accessing
the overlay buffer, and you need to keep that lock until you're done with it.
* The overlay cookie is now an extra member of the ServerBitmap class.
* Removed fInitialized from ServerBitmap - IsValid() now just checks the buffer associated
with the bitmap.
* ViewLayer::Draw() will now handle overlay bitmaps specially and will draw the overlay
color instead of any contents (this is currently in ugly pink, but will become some
dark color later on).
* All what's missing from actually being able to use overlays now is to configure
them so that they are shown on screen. VLC will now show an empty pink window when
overlay video is enabled.

via the graphics driver (but not yet shown on screen).
I probably got the meaning of the "overlay count" wrong - I guess that you
can allocate any number of overlay bitmaps, but can only see "overlay count"
on screen at a time (right now, I only allow to create "overlay count" bitmaps).
Stephan?

class name. Also returns the actual error from the
BMessage::AddData() if there was any. Please people, correct
code like that if you spot this elsewhere and don't write
such code anymore.
* the BMessage constructor should be more robust.
* the copy constructor takes the possibility into account
that BitsLength() does not match.

* added NOTE to BBitmap::LockBits(), has anybody some insight into this?
Otherwise we need to write a test app to discover its secrets... :-)

all teams in serveral server areas, and instead of having to eventually clone
them all several times in BBitmap, we now have one or more areas per team,
and BBitmap will only clone areas once if needed. As a side effect, this
method should be magnitudes faster than the previous version.
* This method is also much more secure: instead of putting the allocation
maintenance structures into those everyone-read-write areas, they are now
separated, so that faulty applications cannot crash the app_server this
way anymore. This should fix bug #172.
* Freeing memory is not yet implemented though! (although all memory will
be freed upon app exit)
* There are now 3 different bitmap allocation strategies: per ClientMemoryAllocator
(ie. via ServerApp), per area (for overlays, not yet implemented), and using
malloc()/free() for server-only bitmaps.
* ServerBitmap now deletes its buffers itself.
* Cleaned up BBitmap and BApplication a bit.
* The test environment currently doesn't build anymore, will fix it next.

into account when copying to the same color space (new code isn't that fast,
but it works).
* BBitmap::ImportBits() did not take the specified offset into account at all.
This fixes bug #313.

* Added some comments
* Added some checking to avoid noop shifts
* Added buffer length checks
* Implemented (as Stephan suggested) a version of ConvertBits() that takes offsets.
This new version allows to move a region of the source into a region (possibly not at the same point) on the dest while converting colorspaces on the fly.

I've put it into ColorConversion.cpp and moved PaletteConverter there too, cleaning up Bitmap.cpp.

I get to it again in the next weeks).

Some cleanup. BBitmap::Cleanup() doesn't ask for a reply from the server anymore
(why should it care, anyway?).

Qemu - the loop to initialize the system color map takes two seconds over here.

to LinkReceiver, LinkMsgSender to LinkSender, and put everything into the
BPrivate namespace.
Made AppServerLink a cheap object - it will use the applications receiver/sender
and not create its own buffers.
Fixed broken communication stuff here and there (mostly Font.cpp).
Put the newly introduced set|get_system_colors() into the BPrivate namespace -
please don't introduce private functions into the public namespace!!!
Also fixed their broken communication use, as Darkwyrm obviously forgot about
it again: the sequence Flush(); GetNextMessage() without error checking is
purely wrong and can make the app hang and/or crash! :-)
Other minor cleanup.
The input_server used some test mode with the haiku build target which is
probably wrong.
Hopefully I did not forget anything this time.

several things to work without a running app server (the Storage Kit to
begin with).

Added app-side support for font list
Added mostly-empty global font functions and documented them
