event/x11: Epic clean up

Browse Source 
Event translation is now done where it belongs: we don't need a massive
switch in a file with direct access to private structure members.

So long, event_translate(); and thanks for all the fish.

* glXCopySubBuffer blits happening.
*
* The problem stems from the fact that rectangles for the
* blits are described relative to the bottom left of the
* window and because we can't guarantee control over the X
* window gravity used when resizing so the gravity is
* typically NorthWest not SouthWest.
*
* This means if you grow a window vertically the server
* will make sure to place the old contents of the window
* at the top-left/north-west of your new larger window, but
* that may happen asynchronous to GLX preparing to do a
* blit specified relative to the bottom-left/south-west of
* the window (based on the old smaller window geometry).
*
* When the GLX issued blit finally happens relative to the
* new bottom of your window, the destination will have
* shifted relative to the top-left where all the pixels you
* care about are so it will result in a nasty artefact
* making resizing look very ugly!
*
* We can't currently fix this completely, in-part because
* the window manager tends to trample any gravity we might
* set. This workaround instead simply disables blits for a
* while if we are notified of any resizes happening so if
* the user is resizing a window via the window manager then
* they may see an artefact for one frame but then we will
* fallback to redrawing the full stage until the cooling
* off period is over.
