Alpha masks using an icon instead of a render source failed in most cases.

This issue has been resolved.
Descriptive Problem Summary:
Alpha masks do not render at all. The mouse however seems to interact with it as expected.

Numbered Steps to Reproduce Problem:
Apply an alpha mask filter to something.

Code Snippet (if applicable) to Reproduce Problem:
obj
icon = 'anyicon.dmi'
filters = list(filter(type = "alpha", icon='anymask.dmi'))


Expected Results:
The mask will render.

Actual Results:
It doesn't. (Your mouse disagrees though and will treat the areas that should have been transparent as if they actually are)

Rolling back to 513 solves it.
I need a real test case here. I had a bug report in an earlier build for alpha masks but that was solved already, and in that test case I was able to view the result of the alpha mask properly after the fix.
