Why not create a texture and draw a quad instead of using glDrawPixels (as it is deprecated in gl3)?

Reference -- ogl 3 spec -- (http://www.opengl.org/registry/doc/glspec30.20080811.pdf)

Under "E.1 Pro��les and Deprecated Features of OpenGL 3.0"

"Pixel drawing - DrawPixels and PixelZoom (section 3.7.4). However, the��

language describing pixel rectangles in section 3.7 is retained as it is required��

for TexImage* and ReadPixels.��"
