Alias canComputeFastBounds to affectsTransparentBlack
This moves SkImageFilter's API closer to SkColorFilter's, and also
updates SkRecordDraw's PaintMayAffectTransparentBlack to be less
conservative.
Originally:
-canComputeFastBounds() handled aggregating behavior of the entire graph
but it's a public API
-affectsTransparentBlack() was the private virtual for a specific node
Now:
-affectsTransparentBlack() handles aggregating behavior of the graph and
is part of SkImageFilter_Base (mirroring SkColorFilter_Base).
-added onAffectsTransparentBlack() to clarify the per-node virtual that
they can override.
-canComputeFastBounds() simply returns !affectsTransparentBlack().
There are some usages in our code that I kept using canComputeFastBounds
(e.g. SkPaint's computefastBounds) because it kept naming consistent.
In other places I updated to use affectsTransparentBlack since I thought
that made it clearer why we were checking that behavior.
