stale default framebuffer bound at end of offscreen pass about sokol

[floooh]

I think this is fixed now with the new render-pass API.

@floooh any thoughts on this? we've had to work around it by setting _sg.gl.cur_context->default_framebuffer before the first pass

[floooh]

My plan was to implement #904 as a "proper" but breaking fix (it's most likely the next "big thing" after catching up with a couple smaller PRs, but I can't promise an ETA).

I guess it might make sense to implement your solution in the meantime.

Can you provide a PR (or point me to an existing one)?

It's unclear how to best fix in a general way. Could we just not call glBindFramebuffer at the end of the pass?

otherwise we would need to call sg_desc.context.gl.default_framebuffer_cb at the end of every pass

Could we just not call glBindFramebuffer at the end of the pass?

I'll need to do some git archeology whether there's a specific reason for that glBindFramebuffer, but that might work, yeah.
