Weekly update MS04x13

Important thing was done and part of it was working at first attempt (I love when such thing happens, you write not too small piece of code, compile it and it just works as expected) and it was bunch of changes in rendering.

I now use BSP (which stand for binary space partition) to render sprites that intersect each other or to render objects going through doors. I already tested it on wizard going through door and it works fine - although result is almost not visible, on the other hand, without it, it was right in your eyes.

I hoped that I will have some graphics for doors but I don't :( And because of that, no screenshot this week, but in incoming updates I'd like to show how scene is rendered bit(map) after bit(map). I already have tool to do that and need to find nice example and turn it into gif.

For time being, I will keep gray background.

Ok, so what next?
1. Graphics for doors definitely.
2. More advanced door placement (to avoid placing them where they should not be).
3. Floor generation.
4. Generation of items on different planes.

Given more time, this should be task for couple of days maybe, but this may once again turn into weeks :( But step after step it is getting there.
