Make cata_tiles draw onto the whole available screen area.

Fixes #7438 it works with differing height/width. The tiles at the right/bottom are drawn partially.

Some observations while testing this:

I think #6218 is fixed already. In this version it works as expected.

#2917 is also already fixed - I checked the monster compass, even tiles that are drawn partially are considered outside of the displayed area. Using the list items menu also scrolls the view for items that are outside the displayed area or only partially drawn.

And #1415 was also fixed long time ago.
