In glutMainLoop, the checking of ExecState, and wether it's equal to

Browse Source 
GLUT_EXEC_STATE_RUNNING should not have been at the top of the loop, but rather
right after glutMainLoopEvent returns, after it processes a single event. As it
was, we would be sleeping, waiting for further events even if the user just
called glutLeaveMainLoop (which sets ExecState to GLUT_EXEC_STATE_STOP).

Also fixed a couple cases if inconsistent use of tabs/spaces for indentation
which was causing gcc to emit bogus warnings about misleading indentation
around braceless ifs.
