Workspace project: Matrix painting (v0.2).

[MvGulik]

Although this is not really the place for this.
(looked around for potential alternatives locations but found none. +no more VIPSIP JiscMail.)

Was playing with matrices, but found the matrix values editing inside nip2 kinda troublesome.
So looked for an alternative way to play around with matrices inside nip2 directly ... by painting it.

Not sure if in the end its 'that' useful. Had to create this first of course. But think it should still be a potential nice little alternative nip2 matrix (image-filtering) experimental workbench.

Matrix_Painting.ws.zip (v0.2) -- Fixed some things, +made it nip4(v9.0.5) usable (kinda).

I'm planning to rewrite the menus, and fixing matrix cell edit is one of the big ones. There's a work-in-progress branch here:

... though it'll still suck for large matrices, unfortunately.

(v0.2) Oops, lol. Forgot there is no painting in nip4.
... but, just some idea that cropped up, when it comes to using an image as matrix input.
if/when the painting feature returns. Being able to also paint with negative values, combined with seeing those values in the image view (at some large zoom-in factor) ... it might make it easier to play around with larger matrices in nip4.
