Bug: generated resize bigger than expected
Hey,

I just downloaded the plugin, but I saw that every time I generate different sizes from icons I have in the document the generated icon is slightly bigger or smaller than the canvas / expected size of the icon. 
Example: the original icon was 40x40px, and when I use the plugin the generated one is 38.09x38.09px instead of 40x40px, 30.48x30.48px instead of 32x32px, etc.
The artboard has the right size though.

Is that normal?
Thanks!
