* Initial opengl test window * added core files * some fixes for code comparability with other platforms * more compatibility cleanup * add missing opengl libraries * Basic simulation window works! * try using different define * fix wrapper for better compatibility * Gui is now operational * Finally SIM works on actual freecad models * support drill commands * cleanup python script and add tool profile generation * Now using actual tools specified in the operation. * support mouse wheel and freecad-style 3d navigation * Support accuracy gauge * remove endsimulation reference * show simulation speed indicator * apply clang-format * apply changes suggested by code review * gui items are loaded via QT resource system instead of hard coded * use vector instead of pointer to pass tool profile points * Fix some more formatting errors.
