Texture manager class

[thelusiv]

We need a class that handles textures instead of all the other classes having to keep track of them...I think it should do the following:<ul><li>texture loading<li>texture unloading<li>texture drawing<li>keep a reference to each loaded texture (GLuint)<li>if a request to load a texture is made after that texture has already been loaded, just return the stored reference to the texture (don't load it again)<li>keep up with sizes of textures somehow?<li>simplify the way we handle textures<li>handle reloading all the textures if the texture size changes</ul>what else?
