* framebuffer: avoid gluint overflow GLuint was being initialized to -1 and rolling over to unsigned int max, its defined behaviour but very unnecessery. add a bool and use it for checking if allocated or not. * opengl: avoid gluint rollover -1 rolls over to unsigned int max, use 0xFF instead. * core: big uint64_t to int type conversion there were a few uint64_t to int implicit conversions overflowing int and causing UB, make all monitor/workspaces/windows use the new typedefs. also fix the various related 64 to 32 implicit conversions going around found with -Wshorten-64-to-32
