[2.8pre-259-g974619d] Negative actor scales don't work

Either set by A_SetScale or directly through respective properties, the result is an invisible actor. Technically, this probably isn't a bug since I believe only positive scales are officially supported, but reporting in case it's a simple fix.

Added for XScale. Unfortunately for YScale this would be a lot more complicated because it has to change the actual sprite drawing direction. XScale just meant an additional check to toggle sprite flipping if a negative scale was passed.

I'm curious, what all would need to change about that? TEXTURES has FlipX and Y, can't it borrow from the same place?

No. What needs to be done here is to invert the column drawer to draw from bottom to top - and to be honest - I wouldn't expect it to happen. But on the other hand stranger things have become reality...

XScale was trivial, though.

I don't think I'd call it one of the stranger things to happen since the code is mostly there. Unless Randi takes care of it though it'll be a 2.8.1 fix since I'm not 100% confident with my ability to complete the implementation correctly.

Added. And, yes, it helped a lot that this was already in for decals and wall sprites (though not via negative scale).
