build: update pygfx deps

[tlambert03]

@gselzer

there's one thing that's changed about pygfx/rendercanvas since the last version here and that is that i can't get it to render immediately at the right aspect ratio. any action, even just clicking the canvas, makes it snap into correct ratio. know why?

Because we aren't redrawing the canvas on resize, of course 😆

If you check out the pygfx camera controller, a redraw is only triggered on some actions. One of which is clicking on the canvas. Resizes events don't even call that function, or at least my breakpoint isn't hit when I resize...

I think that before, we were redrawing all of the time, with something like:

    def _animate(self) -> None:
        if self._camera is not None:
            self._renderer.render(self._scene, self._camera)
        # Draw again, recursively!
        self._canvas.request_draw(self._animate)

but we took it out to avoid unnecessary draws. I think a better solution is just to redraw in some event handler that captures resizes.

Rendercanvas should schedule a draw whenever the canvas resizes.

Do you mean to say "it's a bug if it doesn't"?

Do you mean to say "it's a bug if it doesn't"?

Yes, should as if it does not, it's a bug.

[almarklein]

Oh, but I can indeed reproduce that this does not happen with qt. Looking into it.

Fixed in pygfx/rendercanvas#188, and released rendercanvas v2.6.2

Thanks as always!
