mesa: Return LINEAR encoding for winsys FBO depth/stencil.
GetFramebufferAttachmentParameteriv should return GL_LINEAR for the window system default framebuffer's GL_DEPTH or GL_STENCIL attachments when there are zero depth or stencil bits. The GL 4.5 spec's GetFramebufferAttachmentParameteriv section says: "If the value of FRAMEBUFFER_ATTACHMENT_OBJECT_TYPE is not NONE, these queries apply to all other framebuffer types: [...] If attachment is not a color attachment, or no data storage or texture image has been specified for the attachment, then params will contain the value LINEAR." Note that we already return LINEAR for the case where there is an actual depth or stencil renderbuffer attached. In the case modified by this patch, FRAMEBUFFER_ATTACHMENT_OBJECT_TYPE returns FRAMEBUFFER_DEFAULT rather than NONE. Fixes a CTS test when run in a visual without depth / stencil buffers: GL45-CTS.gtf30.GL3Tests.framebuffer_srgb.framebuffer_srgb_default_encoding Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Jordan Justen <[email protected]>
