R8G8B8 means red is the most significant bit.
On a little-endian system, the texture is stored starting with blue.
It is read byte-by-byte (GL_UNSIGNED_BYTE), therefore it needs to be
flipped to GL_BGR.
This makes Demo #2 (texture mapping:
http://www.zanir.szm.sk/dx00-09.html) show the correct colors.
Also, in HL2, it makes Barney's face human color (previously it was blue).
I think Stefan Dosinger saw improvement on some other demos.
There might be more to this. This was changed the other way around not
too long ago. See

It might just be that the glDrawPixels call should've been changed
instead last time. (Shouldn't those simply use the format in
This->glDescription.glFormat in the first place?)
