description
A collection of quite reusable graphics-oriented C++ code. Fairly refined as individual parts, but the package as a whole is a bit casual.
Comprising 29 modules, and about 8500 lines. Mostly classes, but several functions too. Not all tests are included.
module list
general
standalone:
| FpToInt | Int-float conversion functions |
