Adding a PictureResolution option to SkPictureImageFilter

This change adds an option to SkPictureImageFilter to make it
rasterize SkPicture in a resolution that matches the local coordinate
space (equivalent to the record-time device space).

use drawRect when drawing a bitmap with anti-aliasing on a non-msaa target

If the dest isn't pixel aligned, or if a non 90 degree rotation is
present, we need to use drawRect() for drawing anti-aliased bitmaps on
non-msaa targets or the edges won't be anti-aliased as intended.

Note: If the bitmap size is bigger than max texture size we fall back to drawBitmapCommon.

I'm not sure whether or not this will _fix_ the SkMatrix aspect of that bug.
There may be other SkMatrices that we're racing on.  It does cover the obvious
ones, though, and removing the SkTRacy<> wrapper will allow TSAN to show
us any other races.

It turned out to be easier to turn missing optional matrices into I early rather
than late.  I figure this should be harmless.  Recording and playback perf both
look neutral.

nanobench: lazily decode bitmaps in .skps.

This cuts down on tool overhead when running something like recording only,
    $ out/Release/nanobench --match skp --config nonrendering
which doesn't usually ever need to decode the images.

The actual measurements for recording don't change, as the decode is not in the timed section.  It just skips irrelevant code, removing it from the profile and making the tool run faster.

This does, however, make a significant difference for playback speed.  Most skps draw faster with this patch, some slower.  I don't really have a good intuition for what's going on here.  There is a fixed clip acting as a viewport, so there are probably lots of images that don't ever need to be decoded.  Ideas?  Is this perhaps because we're now blitting from smaller, partially decoded source images?

Win8 Debug dashing2_nvprmsaa4
Win8 Debug glyph_pos_n_b_msaa16

Note that the dashing2 difference fixes an erroneously set pixel in the expected.
