Albrecht Schlosser 1fd6f0dd3a Fix STR 3458: "GLUT compatibility mode segfaults" ... ... "when there's no current window". Silently ignore GLUT function calls that need a current window if the current window is NULL, return 0 from functions that return an 'int'. Check if window is shown in Fl_X11_Gl_Window_Driver::swap_buffers(). This would issue "XRequest.nnn: GLXBadDrawable 0x0" on X11 otherwise. Note: the chosen implementation to ignore GLUT calls silently appears to be compatible with GLUT (3.7) whereas FreeGLUT 3.0 would issue error messages and exit. The latter could be implemented as well but would be much more work.		2023-10-07 17:14:11 +02:00
