[Mesa-dev] [PATCH 3/3] mesa: invalidate framebuffer when changing parameters

[Ilia Mirkin]

This fixes dEQP-GLES31.functional.fbo.completeness.no_attachments

When the width or height are 0, the framebuffer is incomplete. We may
also not have been passing the new state down to the driver when the
widths/heights/etc changed. Make sure to dirty the state so that the
framebuffer state is revalidated at draw time.
