Cheers RorrKonn, but you have it the wrong way around, GIMP is doing it properly, it's been done like that for as long as I remember.

• Manga Studio can't do it because the person in charge of features isn't up to the job of realising it should be there in a vector program.
• Adobe Illustrator used to have it until, if I'm understanding Primorge, they realised it's a major deal breaker so decided to charge extra for a plugin.
• GIMP does it right, it's there as standard, it's up-to-date modern tech that designers rely on, I'm a designer myself, so trust me ;-)

For designers, this stuff must snap to the grid :-)

Just remember, GIMP can do it as standard (perfectly), but Illustrator can no longer do it by default, and Manga Studio can't even do it at all.  And Primorge, seriously mate, if what you said is true about them removing it from a program like Illustrator (a vector program), the skin-crawl factor of Adobe just rose 100-fold, I really don't know how you can live with yourself for even having an Adobe product on your system.

Smell the roses mate, support those that support you, not those that screw you :-)
