Here's a perfect example. In the first image, that's the original size.

In the second image, that's the same Bitmap but shrunk. When I create floors and such with it, it remains that size. However, I have no idea how I arrived at that. Anytime I try to repeat it using the Scale, I get really small images tiled together or really blurry images unscaled or using Expand.

How do I manage the size of Bitmaps like I did, by accident, in these pics?
