[3.4RC - Win32 client] Map not displayed properly when number of columns is too high

[PowerWyrm]

If you expand your Win32 client so that the number of columns displayed is high enough and you select Options/Map, the map is not properly displayed. This comes from the fact that Term_wipe_win() doesn't check for td->map_active like all other functions and erases an incorrect part of the window when displaying the full map.

To fix the problem, copy/paste the code from Term_curs_win():

replace

	/* Rectangle to erase in client coords */
	rc.left = x * td->tile_wid + td->size_ow1;
	rc.right = rc.left + n * td->tile_wid;
	rc.top = y * td->tile_hgt + td->size_oh1;
	rc.bottom = rc.top + td->tile_hgt;

by

	int tile_wid, tile_hgt;

	if (td->map_active)
	{
		tile_wid = td->map_tile_wid;
		tile_hgt = td->map_tile_hgt;
	}
	else
	{
		tile_wid = td->tile_wid;
		tile_hgt = td->tile_hgt;
	}

	/* Rectangle to erase in client coords */
	rc.left = x * tile_wid + td->size_ow1;
	rc.right = rc.left + n * tile_wid;
	rc.top = y * tile_hgt + td->size_oh1;
	rc.bottom = rc.top + tile_hgt;

Note that the client completely screws up displaying tiles when the number of columns reaches 255 due to the fact that this number is stored on a byte (see another post about the subject). So the problem is probably masked by another bug in the current code. A workaround would simply be to limit the number of columns to 255, it should give a large enough display.
