When a window is destroyed, always override the fade out so that the finish_destroy_win function can be called.
When a ConfigureNotify event is processed on an unmapped window, don't set the clipChanged = True. Fixes unmap->configure causing flashing during the fade-out.
Don't use windows that are destroyed when restacking other windows or when handling events on a window id. It is possible for the same window id to appear in the window list multiple times if it is destroyed then created before the destroy fade-out completes.
A window can move/resize while it is fading out. Even if you don't delete the pixmap in that case, the fade-out will be shown in the wrong place and the wrong area on screen will be marked damaged when the window is gone without this patch.
When a window that is mapped is reparented away from root, that is the same as it being completely unmapped+destroyed from our persective. The window will no longer be in the same position on screen, and we will no longer want to listen to events on it.
Prior to this, the w->pixmap would not be freed when a mapped window was reparented away from root, and damage would not be updated for the screen correctly.
When a window resizes while it is unmapped, don't destroy it's pixmap, as that kills and fade going on.
If a window is already unmapped (and therefore already fading out, don't override the fadeout with a new one when the window is destroyed.
When a window maps, if it already has a pixmap, this is stale data, so free it so that a new pixmap can be retrieved from the newly mapped window.
-s: server-side shadows (sharp, but follows window alpha)
-c: client-side shadows (blurred, but uses window extents only)
-n: no shadows (this is the default mode)
to do server-based shadows (SHARP_SHADOW). Has code to try and ignore
appropriate errors (helps somewhat). Has code to handle global window
translucency. Lots of other minor changes.
shadows. Speed up shadow construction a bit by using memset. Eliminate
useless INTERVAL code. Use XSync after paint_all to gather more events
per update.
