Original issue's description:
> Fix layer hoisting image filter corner cases
> 
> This CL fixes 5 bugs related to hoisting image filters:
> 
> For image filters the src layer (the one prior to filtering) often needs to be
> smaller then the final layer. This requires the saveLayer's optional bounds
> to be stored (in SkLayerInfo.h and SkRecordDraw.cpp) and then used in
> compute_source_rect and carried around in GrCachedLayer.
> 
> The image filters can add an extra offset to the final draw operation.
> This is now computed in GrLayerHoister::FilterLayer and  carried around in
> GrCachedLayer.
> 
> Filtered layers must use exact matches. This is now done in GrLayerCache::lock.
> 
> The filter cache requires a valid matrix so it can compute the correct offset. 
> This is now done in GrLayerHoister::FilterLayer.
> 
> Filtered layers need to be drawn with drawSprite while unfiltered (and therefore
> hopefully atlased) layers can be drawn with drawBitmap. This is now done in
> draw_replacement_bitmap.
