Avoid iterating all towns and industries when updating station catchment, and scan a limited portion of the map instead.
This provides a modest performance benefit when many towns/industries exist.

Remap sprites start with a count byte followed by 256 entries, but
SetupColoursAndInitialWindow did not take account of this extra byte and
therefore started at palette index 0xC5 instead of 0xC6. This caused the
first colour of each gradient to be incorrect and all shades were actually
1 step lower in the gradient than indicated.
Some windows resize themselves during painting and issue ReInit(). In this case deferred OnResize() causes a visible glitch as the event is handled on the next redraw.
