This port uses a user-editable 16x16 font in the font directory. Feel free to use this in other ports to the game. This port will work with my bigscreen patch, if it is turned on in your varient. Note that this patch is not the same as the code in Zangband. Zangband has a wilderness - and uses an extension to make the trees look right.
Extra code is required to make pillars stand up, and trees look good.
See cave.c, files.c and types.h in Zangband for the modifications that store the extra information for the terrain tiles.
