Hold ALT while re-sizing tokens to create small/tiny etc monster

I went through the whole process of manually creating the attached tokens for tiny Cave Rats via The GIMP and was part way through writing a suggestion to allow re-size smaller than when it finally occurred to me that I could probably use ALT while re-sizing to avoid Snap To Grid much as you can when moving background images. I figure I should post anyway in the hopes that someone searching for a solution can save some time, as I can't find any reference to this "free-size" control regarding tokens.

Alternatively, you can set the grid size to a half or a quarter of what it should be. It wont affect distances since those aren't based on the grid size, and it will let you resize them to a grid that supports tiny and diminutive monsters. (PS, small monsters take up a 5ft spot, tiny monsters take up a quarter)
