gui: Add pixel density selector to canvas size dialog ... 

which will be shown when selected template pixel density don't
match the image pixel density.

Then user can either keep current image ppi and scale the
template or set image ppi to match the template ppi.

Density selector displayed only when template and image ppi
differs and template unit is matches one of real world units
(e.g. inch, mm, etc).
