It still has a clipping glitch (you can see it with a rectangle when rotating: the border gets clipped off) but it does visually appear more 'solid' and expected when aligning rectangular shapes together. I'm going to keep experimenting to find something that keeps the rotated bitmap in tact while still aligning properly. I feel like I probably glanced at a method that needs an edit over and over but haven't realized which one it is yet. I still need to look into the cursor not being properly redrawn as well. I might be stretching or trying to make a connection that isn't there, but something 'feels' related to this and the cursor, like some common reference point is being shifted so that the cursor's area for drawing doesn't reach the left and bottom edges just like the origin doesn't reach the left and bottom edges correctly for the this rotation issue.
