Rename compUpdateWindow to compPaintWindowToParent and split the child
walk to compPaintChildrenToWindow. Calling compPaintChildrenToWindow
allows an arbitrary subtree to be updated, instead of having to update
all the windows. This will be used to make sure all the descendants are
copied to the parent when the parent window contents need to be accessed
in IncludeInferios sub-window mode.
WindowRec has a new member 'damagedDescendants' that is used to keep
track of which subtrees need updating. When a window is damaged,
'damagedDescendants' will be set for all the ancestors, and when a
subtree is updated, the tree walk can be stopped early if no damaged
descendants are present.
CompScreenRec no longer needs the 'damaged' member since the root
window's 'damagedDescendants' provides the same information.

TraverseTree visits the parent before the children. When performing
the automatic redirection updates, the children must be visited before
the parent.
If there are automatically redirected windows on multiple levels of the
tree, updating the parents before the children would cause the parent
updates to use stale data for areas covered by the children. Also
updating the damaged children would re-damage the parent, which would
cause additional walks over the tree.
In the worst case with an unbroken chain of automatically redirected
subwindows, all of which are damaged, only the leaf window would be
properly updated on the first round. Then it's parent would be properly
updated on the second round, and so on. And on every round all of the
ancestor windows would be updated as well, but with stale data.
So with N damaged windows you would end up with (N^2+N)/2 updates,
instead of the expected N.
This reverts commit 648c8871c9.

Various cleanups identified during review of the
X Sync Fence Object patches.
-Correctly handle failure of AddResource()
-Don't assert when data structures are corrupt. Instead,
use a new helper function to check for counter sync
objects when they're expected, and warn if the type is
wrong.
-Use the default switch label rather than reimplementing
it.
-Re-introduce cast of result of dixAllocateObjectWithPrivate()
to kill an incompatible pointer type warning.
-Remove comments claiming protocol updates are needed. One
wasn't true and the other was addressed with a xextproto
change.
-Return BadFence, not BadCounter from XSyncAwaitFence()

Even calling block handler that doesn't do much is costly in arm. It

If the drawable size doesn't match the pixmap size page flipping should

If the window is larger than the pixmap, page flipping might need to
reposition the CRTC somewhere in the middle of the pixmap. I didn't
spot any code that would handle that at least in the intel driver.
Also the root pixmap could then move to some negative screen
coordinates. Not sure if all bits of code could handle that. Perhaps
when composite is enabled screen_x/y would make it work, but without
composite there's no way that it would work AFAICS.
