[Tuxpaint-devel] 1-, 2-, and 3-point perspective line drawing Magic tools

[Bill K. <nb...@so...>]

Happy holidays!  ICYMI, I've recently added three pairs of new
Magic tools that allow you to draw diagrams using 1-, 2-, and
3-point perspective, and to adjust the vanishing point(s) for
those three drawing tools.

They're a _little_ finnicky, but seem to work okay for now.
I'd be happy letting them loose into the world as-is, and
get feedback from "actual artists" (i.e., "not me") as to their
effectiveness.

In the meantime, you can see a demo of them here (note: I was
using a mouse, and my left button seemed to be dirty & acting up;
perfect timing :eyeroll:)

This was inspired by some videos I saw of Krita, which has some
"guide" features which allow for the same kind of perspective
drawing technique.  My hope is that this can be used to help
educate kids learning art.  (A lot of things I've added to
Tux Paint are just "fun", or "in the style of {some artist or
art style}"... but things like this, and the Color Mixer tool,
are meant to be slightly more educational... hopefully ;-) )

Enjoy, and let me know what you think.  Code improvements
welcome.  As usual, I've often done this late at night
(in bed, even!), and I never took a Trigonometry class
(and I had, it would've been 30 years ago :-D ... my day job
does not involve this kind of math, hehehe)
