Snapshot 2.99.912 (2014-06-10)
A final round of features. We have everything from support for variable
cursor sizes, support for the DRI3 and Present extensions, improved DRI2
support, support for Xserver 1.16, userptr from kernel 3.16, and
precursory support for DP multistream transport,

 * Avoid discarding dirty pixels when promoting a migration to cover the
   whole pixmap.
   Regression in 2.99.911

 * Avoid overextending degenerate lines (and consequentially accessing
   pixels outside of our damaged area).

 * Fix subpixel glyph rendering on gen2 devices (830-865 chipsets)
   Regression in 2.99.911

 * Share the global pixman glyph cache between ZaphodHeads

 * Light up all connected outputs, even if their status is unknown, on
   takeover from fbcon. This prevents loss of display after a resume
   on recent kernels, for example.

 * Show the video overlay (when supported by the hardware) across all

 * Do not discard damage when performing "BLT" spans inplace with the CPU.
   Regression from 2.20.10

 * Avoid discarding IO buffers too early during their preparation for a
   new batch

 * Fix fallback handling for displaying large scaled framebuffers (that
   are too large to be scaled by the GPU in a single pass)

 * Listen to external modifications of backlight value and propagate
   the notifications to RandR clients. This should make the GUI report
   ACPI keypresses to change the backlight correctly.

 * UXA: fix pageflips with 3 heads.

 * UXA: do not report a BadMatch error for DRI2GetMsc - as clients are
   often unprepared and die when they get the unexpected error.
