// OpenGL Texture Class
// by: Matthew Fairfax
//
// GLTexture.h: interface for the GLTexture class.
// This class loads a texture file and prepares it
// to be used in OpenGL. It can open a bitmap or a
// targa file. The min filter is set to mipmap b/c
// they look better and the performance cost on
// modern video cards in negligible. I leave all of
// the texture management to the application. I have
// included the ability to load the texture from a
// Visual Studio resource. The bitmap's id must be
// be surrounded by quotation marks (i.e. "Texture.bmp").
// The targa files must be in a resource type of "TGA"
// (including the quotes). The targa's id must be
// surrounded by quotation marks (i.e. "Texture.tga").
//
// Usage:
// GLTexture tex;
// GLTexture tex1;
// GLTexture tex3;
//
// tex.Load("texture.bmp"); // Loads a bitmap
// tex.Use();				// Binds the bitmap for use
// 
// tex1.LoadFromResource("texture.tga"); // Loads a targa
// tex1.Use();				 // Binds the targa for use
//
// // You can also build a texture with a single color and use it
// tex3.BuildColorTexture(255, 0, 0);	// Builds a solid red texture
// tex3.Use();				 // Binds the targa for use
