Subject: Normalize use of DISABLE_SCALERS. Now it really disables all scalers
 except essential Normal1x. Also thumbnails get compiled unconditionally so we
 get them on all platforms, even those which never display them.

Sorted out mess brought to sdl backend by epoc maintainer. He misused
__SYMBIAN32__ where DISABLE_SCALERS is more appropriate.
