Remove assert in tiling code.

Both Zeniko and Malc have said that this causes problems.

Following a hint from malc, the following command causes the
assert to trigger:

win32/Debug/pdfdraw.exe -r0.3 -o out.png ../MyTests/pdf_reference17.pdf 1143

I suspect it's because of the extreme resolution, and the round_rect
call. At any rate, disabling the assert is of no real import.
