add local caching for skia draws
PDFium assumes the lowest common denominator and draws many strings and paths that can be accumulated. Defer canvas->restore() calls until required because the clip changed. Defer text and path draws as long as subsequent calls concatenate additional data. Include debugging switch to allow disabling cache at compile-time while bugs are shaken out.
