When creating a window with recordmydesktop running, the following may happen:
create picture 0x1cd457e0, with drawable 0x1327d1f0
(SetWindowPixmap is called)
destroy picture 0x1cd457e0, with drawable 0x1cd65820
Obtaining format for pixmap 0x1327d1f0 and picture 0x1cd457e0

(II) fail to get matched format for dfdfdfdf
The fix is to update the picture pointer when the window pixmap is changed,
so it moves the picture around with the window rather than the pixmap.
This makes FreePicture work correctly.

As we need to call DamageRegionAppend even for fallback path,
we must initialize the region before do that. Pointed by

Don't call miCompositeRects. Use glamor_composite_clipped_region
to render those boxes at once.
Also add a new function glamor_solid_boxes to fill boxes at once.
