Delete Branch "%!s(<nil>)"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
Broken: Blender 2.75 RC1
Issue:
If you save a Stereo 3D Anaglyph render as a png with RGBA it'll turn all shades of black into alpha.
If rendered as RGB PNG it saves it properly.
HOW TO REPRODUCE:
Render a Stereo 3D Anaglyph version of any scene
Save it as RGBA PNG
All black is now transparent

It thinks that the generation of the alpha channel is wrong.
You think that it is expressed black, but this is because it did not set a light when you render it.
with world light
without light
version 2.75 (sub 1), branch b'master', commit date b'2015-06-16' b'23:38', hash b'81b37f5', b'Release'
Even if a light is set when there is an object behind, alpha channels seem to be different.

blender crashes when I load the file which I attached.
I do not understand the cause.
version 2.75 (sub 1), branch b'master', commit date b'2015-06-16' b'23:38', hash b'81b37f5', b'Release'
I remade it.

@dfelinto, assigning to you, but Ill check on it too, since we should try resolve before release.
@ideasman42 did you manage to reproduce the issue? I just tested it with the official RC1, and things are fine. (OSX)
