Add a straight line / curved line painting features

[VergilUa]

Just purchased ArmorPaint, its a cool piece of software.
So this feature might be already available, but I can't find it.

It would be nice to have a straight line painting feature for the brushes for painting some hard edgy models.

As well as curved line brushes (e.g. bezier).

Holding shift produces rather interesting results:

I think its a bug?

If anyone finds this in the google, I've used AHK (AutoHotkey) script as a workaround to draw a line:

Usage - press tilde (~ or `) key to start a line, lift the key to end the line.
Unfortunately, w/o preview its quite hard to draw them blindly (requires a bit of ctrl+z), but its better than not having line tool at all.

I'm pretty sure it should be possible to implement via plugins, but I haven't digged into them yet.

Added some basic line drawing functionality in latest 0.7 dev builds - hold shift key (brush ruler) + click with mouse / pen to draw the line. Will need more refinement to work better on steep / curved surfaces.

Will need more refinement to work better on steep / curved surfaces.

Its the Angle Reject that is messing around with the painting. Disabling it allows 90 degree edges painting just fine (well, kinda).

Also, lines look like lines only if they're painted multiple times unfortunately. Its either brush itself, or the projection / camera angle. So yeah, it does need a bit of refinement.

It basically paints a capsule between 2 points when 3D cursor is enabled. If the capsule pierces the mesh the stroke is gone due to higher depth than the surface point. 2D cursor does not have this behavior.

Also, lines look like lines only if they're painted multiple times

Thanks for info! Will fix that as well.

I also looking for this feature, I would like to paint some curved crease but I don't know how.
