/** 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.
