Sorry to interrupt your comments, but I thought I'd just mention that the new commits (revisions 2816 and 2817) have broken compiling. I get the following:
../libgag/src/libgag.a(GraphicContext.o): In function `GAGCore::GraphicContext::setRes(int, int, unsigned int)':
GraphicContext.cpp:(.text+0x1972): undefined reference to `gluOrtho2D' collect2: ld returned 1 exit status make[2]: *** [glob2] Error 1\
Hopefully this will be fixed soon. master branch, I thought, was never supposed to break 90% of the time, let alone when compiling (the first step) :P
