PicturePlayer: add option to configure full view resolution

Usually pictures were displayed on the same resolution as the current
skin. Now the resolution of a picture been shown can be configured. During
fullview the desktop overlay will be temporarily be switch to the
configured resoltion during the picture been shown.

This makes it possible to view the picture in full-HD even when your skin
is not in full-HD.
Revert "PicturePlayer: add option to configure full view resolution"

This reverts commit 0a0d9fc19398804e96a35086974e25fb95c6081b.

Changing the resolution leads to a re-assignment of the graphical
acceleration buffer making all accelerated pixmaps invalid when they are
removed or replaced (picons).

After a resolution change you are not able to zap anymore because you get
a GSOD at the moment memory is made free for the Picon.

gdi: Add UnmanagedSurface struct to get rid of "type" member

gSurface had a misleadingly named "type" member which indicated
whether or not this surface needs to free its resources.
Get rid of this member and use an unmanaged base class, then it is
known compile-time which need cleaning up and which don't.

And a minor performance improvement in lookup function.
