Neil Roberts 520ccba49d Query the framebuffer stencil bits instead of assuming it's global ... Previously when the context was initialised Cogl would query the number of stencil bits and set a private feature flag to mark that it can use the buffer for clipping if there was at least 3. The problem with this is that the number of stencil bits returned by GL_STENCIL_BITS depends on the currently bound framebuffer. This patch adds an internal function to query the number of stencil bits in a framebuffer and makes it use that instead when determining whether it can push the clip using the stencil buffer.
