Dynamic Alpha mapping

An example on making a background into tiles that can have their alpha's changed.

This has been accepted on a good will basis since I don't think any of the mods have GM8.1. If there are any significant problems, do tell us and we'll do our best to rectify the issue.

None of the mods have 8.1? Keep with the times!

This is an interesting concept, one I haven't seen before. While it seems to work, you should really consider providing documentation, including the usefulness of this sort of thing, as well as examples of its usefulness in action. Because as of right now, all I can see it being used for is taking a background, using this as a tool to convert it to tiles, and saving the tileset, when we can do something similar (albeit a little less convenient) in the sprite/background editor.

We could use a little explanation as to why this is useful.

I have 8.1 on my other computer, but then I remembered you guys don't like it when I moderate games (or in general).

So, yeah.

I was actually going to use this in a map editor so that the user could texture a block and then change the alpha of different portions of it. Sorry for the lack of documentation, I didn't really know how to describe this nor did I think about any other use other than a map editor. I think with a little modification this could perhaps be used to change the alpha of a portion of a platform dynamically in-game, like if it was hit with a projectile, or if the map was somewhat dynamic. I could update this and include those kind of features if you guys like.
