This adds a new texture memory allocation header, texture_memory_alloc2.hpp, with two of each memory area. This also adds two new examples, "cube_textured" and "cube_vq" that demonstrate using the new texture_memory_alloc2 to perform CORE rendering, geometry transformation, and tile acceleration concurrently.
