GLibPPC is a graphic library for Pocket PC. Its main goal is to simplify developpers' work by providing primitives and recurring functions for games, demonstrations etc. It is the first library which provides the load of the CPU in real time, a vital indicator when one wishes to optimize the graphic performances of Pocket PC.
Made from GAPI (it does not use other libraries as it often happens), it is very powerful. It is of course free, and being developed by a French-speaking team the support (documentation, forum etc.) is French-speaking too.
