Bruce Evans 80b4b86eb3 Make libvgl mostly work without superuser privilege in direct modes by ... not doing any unnecessary PIO instructions or refusing to start when the i/o privilege needed for these instructions cannot be acquired. This turns off useless palette management in direct modes. Palette management had no useful effect since the hardware palette is not used in these modes. This transiently acquires i/o privilege if possible as needed to give VGLSetBorder() and VGLBlankDisplay() a chance of working. Neither has much chance of working. I was going to drop support for them in direct modes, but found that VGLBlankDisplay() still works with an old graphics card on a not so old LCD monitor. This has some good side effects: reduce glitches for managing the palette for screen switches, and speed up and reduce async-signal-unsafeness in mouse cursor drawing.		2019-04-20 20:29:03 +00:00
