feature request: pixel-perfect line mode

[pixeljetstream]

Currently lines snap to some fixed angles via shift, with pixel perfect mode you would always get the closest line that has a "regular" stepping pattern (increment every N pixels / increment N every pixel).

I've played with a little code myself
https://github.com/pixeljetstream/luajit_gfx_sandbox/blob/master/samples/gl_pixelperfect_line.lua

you can run the sample from the "runtime" directory of the repository via "luajit ../samples/gl_pixelperfect_line.lua"

@dacap could it be what was implemented is not what this feature request is about? At least 1.2.6 still only allows a few directions with angle snapping, instead of many more. Ideally the line tool gets the "pixel perfect" checkbox that the brush tool has, which then would enable this line snapping permanently instead of using shift. Feel free to derive from the code I provided in the above sample

Yeah, the line algorithm was fixed but it still needs more angle snapping (new issue #1641 same as this I guess)
