Abandoned:  Ran out of time (And motivation) [Notes]

I don't think there is much to salvage or take away from this Ludum
Dare.
Everything was quick and dirty, using deprecated opengl.
I did however try a few new things: exporting image to .c file from
gimp, and using the Tiled map editor, and hacky json import code.
Lessons learned:  Get the maths library in faster.  Get the image
loading in faster.
Next Time:  I think I will use/publish a base code for SDL and Opengl
instead of re-re-writing it all from scratch.
