This enables checking all text to see if it either represents a valid reference or is a word in docs/spelling.txt . Expressions are checked for validity as well. There are a few shortcuts (marked with TODO): - typedefs aren't resolved, so cheats are added for SkVector and SkIVector. - operator overload detection is incomplete - constructor detection is incomplete - formula definitions aren't detected Found and fixed a bunch of spelling, usage, and incorrect or obsolete references. A few comment changes are needed in include/core to get this to work, mostly centered around recent SkPaint/SkFont edits.

Stack helper class calls SkCanvas::restoreToCount when SkAutoCanvasRestore
|
|
goes out of scope. Use this to guarantee that the canvas is restored to a known
|
|
state.
