Various graphic bugs

[Ters]

There has been some graphical bugs lately. The first I noticed was that some tracks and vehicles suddenly were invisible (r7552?). Dwachs seems to have fixed that (r7577), but after that, I noticed that some things were bleeding through other things. In particular the arches of pak64's railroad viaducts are visible through the eastern and southern ramps.

Digging 3 levels deep can cause "blind" spots, that get overwritten like in related picture.

@Ters the graphics problems with underground mode should be fixed in r7582

@captain crunch: I do not know how you did this, digging so deep should not be possible and is known to yield to such problems.

Just dig. It's not more difficult than that. You may have to go into sliced underground mode to get the cursor into position once the bottom of the hole disappears "below the horizon", though.

Yes, indeed it is like this and now I remember that there had been a maximum allowance of height difference between adjacent tiles of two levels in former times which would pop up an information window stating aforementioned limitation, preventing from digging deeper.

As part of the double heights code the two level limit was extended to four, when I changed that trying to extend the height difference beyond that still generated a warning window saying that wasn't possible I think.

A height difference between two adjacent tiles of at least three levels was possible before double heights, although you had to be a bit more clever.
