- Changed directory structure significantly, moving gfx api implementations to fennec/renderers

Browse Source 
- Began new overarching window interface
 - Began outlining renderer interfaces
 - Began a binary tree implementation in bintree.h, this will act as a generalized binary tree, then red-black tree will be implemented on top of it for sequences (ordered sets)

A user should never have to specify these and should be automatically generated by the respective components.
Textures for 3D rendering are stored in various buffers with sizes of powers of 2. Ratios of `1:1`
and `2:1` are allowed. The `2:1` ratio is specifically for spherical and cylindrical projection. UVs
may be transformed to use a `2:1` as if it were `1:2`.

Cubemaps and 3D textures may only be `1:1`.
