[FEATURE] Manual resizing, by numerical values, of the width and height of a graphic object placed on the svg editor

[robsori]

Hi. I propose introducing the possibility of resizing a graphic object placed on the svg editor by numerical values. More precisely, I mean changing the values ​​for "width" and "heigh".

Reason: When we have several graphic objects to which we must assign the same dimensions, it is very difficult to find the same size just by manually resizing the graphic object. Note: An external graphic object, dragged by drag & drop on the svg editor displays these useful values ​​for resizing: "width" and "heigh".
