1. updated makefiles to build libOSMesa as well as libGL these are improvements to fbdev-glut 1. mouse cursor will timeout and be invisible if not being used 2. do not restore colormaps to truecolor targets, this causes problems at exit on my g450 3. fixed a crash when cleaning up from failure by munmaping what had not yet been mmaped 4. Resize event handling is improved, the resize function is not invoked from a signal handler now. 5. The main loop can detect if it is running very fast (greater than 2khz) 6. keyboard up and special up events are generated from stdin input mode and if it is also not redrawing, it sleeps 7. corrections in escape sequences for function keys for stdin input
