Detailed Description

Implements an Image using OpenGL.

This class contains a texture handle bound to the data given to the constructor; it draws a textured Quad to the screen.

Image
Note:
Width and height are not limited to powers of two; non-power of two images will be converted internally.
Todo:
Check the correctness of the generateTexture function on big endian systems (ppc)
