TriangleSurfaceView Null Pointer Crash

[pattch]

Currently the most common crash, should be fixed ASAP

(TriangleSurfaceView.java:46)

Line 46 used to be:
if(handler.getProcessedImage() != null) {

I think this caused the app to crash when handler was null. In order to prevent this from happening, I've changed line 46 to be:
if(handler != null && handler.getProcessedImage() != null) {

This will short circuit if handler is null, so the second half of the condition won't execute. Hopefully this will fix this bug, but since I can't reproduce the bug myself I'll leave this bug open for now.
