This singleton is based on the same pattern as VlcManager or VoutManager.
It is intended to load and cache art for the whole skin.
Caching makes sense because 1/ several controls within a skin can display
the current art, and 2/ art is likely to be reused by successive inputs
(music album, repeat). Yet, caching is limited to two art for memory reason.

 - implement mouseOver (forgotten in prior commit)
 - picture rescaled only when size changed (better performance)
 - some cosmetics

The height of a control associated to an animated image is not the height
of the image but the height divided by the number of subimages.

Seriously, FFmpeg is way better and free...

It fixes a segfault when the directx/direct3d device is lost at the wrong time
or cannot be restored soon enough (close #3647).

There is a little difference in Direct3DLockSurface as it now also
sets the height field, but it should have no functionnal changes.

IDirectDrawSurface2_UpdateOverlay may fails, in which case vlc should simply
retry later.

This reverts commit 7c93516a.
It is useless as 6adc3961 added it already.

Do not try to delete a callback and/or a mutex that do not exist.
The goto error paths still look a bit suspicious, someone should
double check them.

This doesn't make it usable though, but noone seems to care anyway...
WARNING: this is a HUGE hack. It will kill yourself and your kittens

This was fixed after 1.1.0-RC.

fullscreen is now managed (activation and deactivation) in skins2
 exactly as it is done in qt4.
    - activation when a VOUT_WINDOW_SETFULLSCREEN is received
    - deactivation when (and only when) a vout_window release is received.

If 0.8.8 is detected and --enable-mod is passed, it will error,
if --disable-mod is passed, nothing will happen
else it will autodetect. This is mostly like all other PKG_ENABLE_MODULES_VLC
detections
