Opengl image warping

WebA texture is an OpenGL Object that contains one or more images that all have the same image format. A texture can be used in two ways: it can be the source of a texture access from a Shader, or it can be used as a render target.

This is important because OpenGL expects only a single pointer to all of the memory for your image. Since we want to be able to access the memory as a 2D array, though, we create a simple array of pointers to the data for each row.
