tdf#147014 Image missing due to integer overflow
32-bit awt::Point/Size/Rectangle cannot fit size of 1M rows with
larger (eg. 5x the usual) height, and could overflow.
This causes problems in 64-bit Linux builds and, since the
following commit, in 64-bit Windows builds:
3d90997fb6f232d8008df4d166d7b97b869c200f
For now, clamp possibly overflowing values to 32-bit.
