Found doesn't like non-whole numbers

[u2mad]

Foundry doesn't seem to like decimals anymore, so unless you get lucky while trying to draw a square, foundry throws an error. My fix was to put in: gridPix = Math.round(gridPix); //round gridpix to a whole number at line 993 & 1052, just before the if (gridPix >= 50) { line.
