Short description of error
Island margin in smart UV project does not take into account the scale of a scene set in scene/ units panel.
it only works for "default" units when unit scale is 1.0

Exact steps for others to reproduce the error
1.open blender
2.add default cube (2,2,2)[meters unit] if blender is not in factory settings
3.in edit mode do smart UV project and change island margin to 1 and note the margin between islands
4.now change unit from meters/metric to centimeters/ metric
5.do smart uv project with the same settings as above and note the margin ---> it is ok in both cases (expected result) as in meters unit cube has 2/2/2m and in cm unit has 2/2/2 cm because blender alone changed displaying cube from meters to cm
6.now staying in cm units scale the cube 100x and apply scale to have cube in initial size of 2/2/2 meters, but now in scene scale in cm
7.do smart uv project with island margin with 1 ----> note how small the margin is and it does not correspond with earlier results, it did not take into account the scale change as it should be in my opinion. the effect should be the same no matter scale is set or applied
