Description Jared 2015-02-23 22:33:47 UTC 
A set of C preprocessor macros and floating-point mathematics routines.

The floating-point routines are styled after SGLIB: set a few preprocessor macros, include the relevant file (either .h or .xmacro), and use the files as appropriate. They need to be adapted to the SDL build system.

The routines and macros are used in a un-committed "pixel perfect" subdivision-area-based textured-triangle renderer. The renderer is intended to support [1734], and these files are in turn intended to support the renderer.

Used to get rid of preprocessor warnings if you invoke the header several times. Used by common_float.c

Common macros and floating-point functions

I got tired of the debug messages, so now there's a simple report formatting system to provide nesting-dependent prefix-whitespace.
