In 507.1256 to 507.1258, /areas don't always draw over the entire region that they should. It seems to be an issue with opacity.
Problem does not occur in 507.1254, so it's likely related to Area Icons Only Appear Left-most

Numbered Steps to Reproduce Problem:
1) Create a /area type with an icon and a layer above turfs
2) Place the area on the map, and place some opaque objects around it
3) Walk around the opaque objects in the Webclient and notice that the area fails to draw correctly in certain positions.
Code Snippet (if applicable) to Reproduce Problem:
WebclientAreaIconTest_src.zip
Expected Results:
Area icon should display over any visible tile that it is placed on.
Actual Results:
Area sometimes vanishes when opaque objects are nearby even if the tile is visible.
Does the problem occur:
Every time? Or how often? Every time in the same positions
In other games? Test project included
In other user accounts? On admin
On other computers? Unknown
When does the problem NOT occur?
In DreamSeeker, or when no opaque objects are nearby.
Did the problem NOT occur in any earlier versions? If so, what was the last version that worked? (Visit http://www.byond.com/download/build to download old versions for testing.)
Problem does NOT occur in 507.1248, 507.1253, 507.1254.
Areas icons were even worse in 507.1255, leading to Area Icons Only Appear Left-most.
This sub-issue then appeared in 507.1256
Workarounds:
Not investigated.
