Via the 'Pixel Preview' option, Adobe Illustrator supports dual-state 
designation where a vector graphic can be created while the bitmap 
rendering is in full consideration.

This is valuable to ensuring 16px icons, for example, render with the 
utmost clarity.

Is this type of workflow supported on any open-source software?
