+ canvas that does the same thing: alter SkPaint fields.
+
+ onDraw*() functions may have their SkPaint modified, and are then
+ passed on to the same function on proxyTarget. THIS BREAKS CONSTNESS!
+
+ This still suffers one of the same architectural flaws as SkDrawFilter:
+ TextBlob paints are incomplete when filter is called.
