SVGAndroidRenderer.processMaskBitmaps is very slow

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Render the attached test.svg using renderToCanvas

What is the expected output? What do you see instead?
For a small file like this, I'd have expected a few ms to render. Instead, it 
took 200ms - 300ms. Using renderToPicture, and rendering the picture it was 
only 15ms.

I profiled it, and processMaskBitmaps was the major bottleneck. Instead of the 
custom processing, I'd guess drawBitmap using a PorterDuffXfermode would work 
here, too. E.g. paint.setXfermode(new PorterDuffXfermode(Mode.DST_IN));
