4c967c5fbc GRAPHICS,SDL: Revision to scaler API 
oldSrcScale() is now unified with scale(). Use enableSource(bool enable)
to switch functionality. Partial screen updates are also posible because
of this.

initialize() had its prototype changes although it is functionally the
same.

setSource() no longer has a type parameter, removing support for
multiple source surfaces. They weren't useful anyway.

useOldSrc() was renamed to useOldSource() to conform to the names of
other functions.

c5c5662330 GRAPHICS,SDL: Change oldSrcScale api 
More bookkeeping is kept in common scaler code instead of the backend.
Plugins inheriting SourceScaler will have this functionality.

TODO: Some new functions may still be able to be combined to simplify
the API.

a4741a7268 GRAPHICS: Template Edge plugin over pixel format 
calcPixelDiffNosqrt is the only function with a valid implementation.
The rest of the templated functions just have skeleton templates (for
now).

592617e2ce GRAPHICS: Add Edge2x/3x scaler 
This currently does not conform to coding standards and contains a lot
of dead code (This will be fixed). Thanks to Eric Welsh for the original
patch.
