So, idea is pretty simple - right now it is possible to set scale parameter only to 25, 50 and 100%
But it not always works good with drawings, and some part of original picture can be cut. In my opinion, custom scale parameter can be pretty good thing.
Also, if we don't need any tools - it may be good idea to hide them, so embedded picture would be seen as is, without distracting buttons.
