In order to stop the release of incomplete BGR patches, I am

I don't have any paticular favourite pixel formats, but qemu now has [at
least] 3 different sets of low-level pixel conversion routines (vga, tcx and
pl110). If you're feeling really enthusiastic it would be nice if they could
be unified :-)
It's one of the things I've been meaning to look at when I've nothing better
to do, but haven't got round to yet..

Just curious...
Are you using an OpenGL directdraw surface for the graphics emulation in
Qemu?
If not, then consider the benefits:
1. It is much faster than any native graphics 2D/3D primitives like
Windows GDI
2: It gives full control over things like window or fullscreen mode in
any (almost) resolution and color depth.
3. It is operating system independent.
4. It handles things like RGB, BGR, 24bit, 15bit, 16bit, 8bit, alpha
channel etc in hardware, all you have to do is select the pixelformat
you like to use for the buffer and OpenGL does the rest - lightning
fast, minimum CPU-load.
My suggestion would be to write a frontend similar to VMware's for Qemu
in Lazarus. Why Lazarus?
1. The fantastic GLscene is available for Lazarus making
OpenGL-programming easy. Try: http://www.skinhat.com/3dpack/
2. With Lazarus a RAD graphic frontend based on OpenGL can be made and
directly compileable for most operating systems without need for
modifications.
Hope someone likes the idea, otherwise I will have to do it myself if I
can find some spare time.
