Subject: Add an explicit FlushDrawing method to Surface that should be called
 after completing a bitmap. Currently only has a real implementation on
 Direct2D. Avoiding implicit flushes inside Copy and FillRectangle produced a
 23% speed improvement on files with about 1 indentation guide per line as the
 drawing pipeline was being flushed for each indentation guide.
