[ANNOUNCE] xf86-video-intel 2.20.19

[Chris Wilson]

A quick release as the last broke USB DisplayLink slave outputs badly. The
performance of those displays was unusable due to a inadvertent change that
caused us to flush the entire scanout over the USB for every drawing
operation.

 * Implement the GNOME Build API. A couple of minor changes to make
   integrators and distributors lives a little easier, or at least more
   consistent.

 * Correctly offset inplace trapezoids for subwindows, such as the GTK+
   close button after it has a background image uploaded.

 * Explicitly prevent ring-switching for synchronized rendering to
   scanouts (for vsync).

 * Clip dirty region to slave pixmaps (otherwise UDL is nigh unusuable)
