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.

8baa92a190 SDL: Fix overlay while using oldSrcScale 
The _destbuffer was overwriting _hwscreen even when the overlay was
visible.

3b408c2d87 SDL: Use an extra buffer for oldSrcScale so it is not confused by AR 
If the two source images match, the scaler assumes there is not update
and does not draw to the surface. However, AR correction depends on a
redraw, so the scaler always writes to _destbuffer which is then copied
to _hwscreen to be AR corrected.

ffb52288a9 GRAPHICS: Add useOldSrc and oldSrcScale to scaler plugin API 
This allows plugins and backends to optionally pass the previous frame's
source image so that the scaler can only update the pixels that need to
be updated.
