Presently an item in the art library can have its size set only in grid squares. It would be useful for things that aren't maps or tokens (eg, a picture you want to drop on the VTT, to be able to set these in pixels, and when dropping them (on token, gm or map layers at least) have that honored, rather than snapping them to conform to the grid. This should not be limited to the original size. A 2560x1440 image in the library could be set to drop as 512x288 (1/5th size), for example. Note: I'm aware that you can set the size in pixels after dropping, but by then you've lost the original aspect ratio because it snapped to grid.
