Bug 702032: Fix overflow problem in scan converter.
Very wide regions to be filled (> 0x80000000) can cause problems
with overflow in clipping calculations, causing regions to be
filled 'the wrong way' (i.e. from -ve to x rather than from x to
+ve).
Fix this by tweaking calculations to promote to 64bit 1 step
earlier than before.
