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. git-svn-id: http://skia.googlecode.com/svn/trunk@4659 2bbb7eff-a529-9590-31e7-b0007b416f81
