I'm test the OpenGL texture with 3 video graphic adapter:
ATI Radeon, NVidia and Intel GMA and
I see that GL_BGRA_EXT is fastly that GL_RGB for 2 times !

Only I see that performance, or anybody test this too ?
It's also a reason to not use AlienImage and read the texture files with QImage, because QImage::bits is GL_BGRA by default without any conversions.....
