Icon glyphs does not handle standard transparency.
The new Icon Editor does not handled the standard PNG transparency (see screenshot). On the image below, all the "black area" should be transparent.
Above is what I see in the LabVIEW Icon Editor.
This is what I should see (this is from windows explorer)
Additionnally, I just noticed that the white color is consider to be transparent (this is somewhat unexpected). I understand that white outside icon area are considered to be transparent (for the resulting icon), but when I take a screenshot and all my white pixel are transparent this is odd.
Note: I will see if I can fix this transparency issue.
