filters. Instead of passing in AutoScratchTextures for temporaries, we allocate
them inside the function and detach() after rendering. Since the functions now
return a ref()'ed texture, we no longer ref() the result in filter_texture().
Also, the imageblur gm was passing a paint with an image filter both to
saveLayer()/restore(), and to every text draw call. Back when only restore()
was applying filters, this was fine, but since we're now applying filters on all
draw calls, this means we're double-blurring in this GM.
I've reverted the Mac baselines for the imageblur GM to their previous versions;
hopefully this will be correct.
