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.
