Cause

The mod info screen only has room for a total of 9 dependencies and conflicts, and it assumes there will be fewer than that many. If there are more, they will overflow the dependencies box. If there are a lot more, they can overflow the screen and crash.

I think I couldn't conceive of a mod having more than 9 dependencies+conflicts when I wrote this. Now we have crazy mods like the RP1 express stuff with way more.

Changes

• Formatting.ConvertCoord now coerces all coordinates to appear on-screen, so if we have other layout problems in the future, they won't cause a crash
• ModInfoscreen.addDependencies now allocates its 9 lines of text proportionally between dependencies and conflicts, and limits the size of the text boxes to fit within that range. If this isn't enough room, the text boxes will display scrollbars. The user is not able to scroll the box because we already use the scroll bindings for the description box, but hopefully they won't care.
