Change in large pcolormesh clipping in 1.4.3 #5370
Description
While upgrading Cartopy's test images (SciTools/cartopy#354), there seems to be a change in large pcolormesh clipping in 1.4.3. It is bisected down to 44ff97e (note: you also need to apply 86824c3 to fix the typo), which does achieve the desired speedup, but also changes clipping slightly:
It does not just affect the above because of the strange shape. Even the simpler Mercator projection ends up clipped differently:

Cc: @pelson as author of the change. Any thoughts as to the cause? Just a difference in order of floating point operations, maybe? I can see how the old behavior is probably a little more correct, so it would be nice to revert to that and keep the speedup if at all possible.
