Now that we have our shaders loaded in a new, more object-oriented way, we're a third of the way to having textured objects in our program!
In this tutorial, we'll add a function to send textures to the graphics card and write a new class to give us a cube with texture coordinates. Unfortunately, we'll need to wait for part 3 to put these to use, but I'll try to hurry it along (summer is almost here)!
