hey, first PR here.
This mostly undoes the dependency inversion from pygfx/rendercanvas#153 by adding a classmethod that avoids the existing constructor and hopefully writes all required attributes.
Includes the same example but is much simpler as offscreen canvas context sorta works out of the box (I think it skips frames randomly as there is no managed swap chain).
I did a few tweaks to shadertoy to make it work, so this won't work with the main branch as is. Maybe it should just be the wgpu cube instead since this doesn't need the rendercanvas protocol and should just work with a manual render target. It also works if you create the texture from the
.wgpu_objectof agfx.Texturebut that is very constructed...I am still new to this codebase so I just included everything that looked relevant. I didn't try any of the resource functionality.
Open for discussion and commits into this branch (always), don't indent to make decisions as I am only tangentially using pygfx via fpl and real users might need different functionality. I also want to bring this sorta functionality to the shadertoy project, but it would be great to decide on a common interface.
