TextureUpload

===========================================================================

DESCRIPTION:

This sample code demonstrates the fundamental techniques to obtain optimal 

texture upload performance. There are two levels of optimizations here:

- The Apple Client Storage extension allows you to eliminate a texture copy 

at the client. 

- When working with non-power-of-two texture target (GL_TEXTURE_RECTANGLE_EXT), 

you may use the Rectangle Texture extension and the Apple Texture Range 

extension to further optimize texture upload performance.

Note, the first level of optimization applies to both GL_TEXTURE_2D and 

GL_TEXTURE_RECTANGLE_EXT targets; the second level of optimization applies to 

the GL_TEXTURE_RECTANGLE_EXT target only.

See the OpenGL Programming Guide for Mac OS X for more information, in 

particular, the chapter of "Best Practices for Working with Texture Data".
