-/** SkDrawFilter is likely to be deprecated; this is a proxy
-    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.
