[Spice-devel] [PATCH 10/11] spicec: disable stencil test with primary fbo

[Marc-André Lureau]

Updating commit message for rationale:

The primary buffer doesn't use stencil test. However, this should be
explicitely disabled, since the canvas might change stencil state, and
this will affect primary stencil buffer, making some of further update
operations clipped in unwanted ways.
