If I load two pixmaps. Make one of them into a texture. Then wants to update that one with the other pixmap, how would that work?
I have tried this approach, which doesn't work. The texture just gets updated with some garbage pixels:
Anyone got working examples of doing this?

tmp1 = LoadPixmap( "test1.png" ) tmp2 = LoadPixmap( "test2.png" ) tex1 = bglTexFromPixmap( tmp1 ) glBindTexture GL_TEXTURE_2D,tex1 glTexSubImage2D( GL_TEXTURE_2D, 0, xOffset, yOffset, width, height , GL_RGBA, GL_UNSIGNED_BYTE, tmp2.pixels )
