Wessel Dankers d84b572b8c vo_opengl: always dither
Dithering was disabled if the input bit depth was not larger than the
output bit depth of the screen framebuffer. But since scaling, RGB
conversion, and other filters change the number of significant bits
anyway, dithering could still benefit image quality even in these
cases. Always do dithering, unless dithering is completely disabled.

The original intention of this mechanism was not to change the image
needlessly when playing video that matches the native bit depth of the
screen.
