Loki Rautio 087b7e7abf Revert "Project modernization (#630)" 
This code was not tested and breaks in Release builds, reverting to restore
functionality of the nightly. All in-game menus do not work and generating
a world crashes.

This reverts commit a9be52c41a.

// representing a range of 0 to 1.9921875
// rgb is 4:4:4 RGB
// umin, vmin are 3:13 unsigned fixed point UVs reprenting the min u and v required by the quad
// ud,vd are 8-bit unsigned fixed pont UV deltas, which can be added to umin/vmin to get umax, vmax
// and therefore define the 4 corners of an axis aligned UV mapping
// i is a code per vertex that indicates which of umin/umax should be used for u, and which
// of vmin/vmax should be used for v for this vertex. The coding is:
// 0 - u = umin, v = vmin
// 1 - u = umin, v = vmax
