fix parchment tearing

Simplest fix: fix parchment tearing by rounding coordinates where textures must meet

For skybox, I assume a patch like

--- a/Assets/Scripts/Internal/DaggerfallSky.cs
+++ b/Assets/Scripts/Internal/DaggerfallSky.cs
@@ -240,8 +240,8 @@ namespace DaggerfallWorkshop
             float yShear = (Mathf.Tan(angleXRadians) * zoom) * 0.50f;
             float scrollY = Mathf.Clamp(baseScrollY - (yShear * Screen.height), -height, 0f);
 
-            westRect = new Rect(westOffset + scrollX, scrollY, width, height);
-            eastRect = new Rect(eastOffset + scrollX, scrollY, width, height);

         }
 
         private void DrawSky()

could help, however I don't like adding code for a problem I've been unable to reproduce...

This is very good and certainly helps fix the problem almost completely. I was able to still create a small tear using this, but it's very uncommon now and I had to work really hard to find just the right spot. :)

Happy for a PR for sky if you have time. Thank you again!

Yes, I can still create the issue in 1440x960

Not sure why it still happens in that case...

Would be interesting to step back through Unity versions to see exactly where this started. The change notes for that release might offer some clue.

I suppose it's possible this will be fixed by a Unity point release later. Other than a few minor tweaks like this PR, I'm not keen to overhaul UI layout just yet to work around problem. I have a sense this one will be a fix that finds us rather than the other way around.
