Subject: mesa: return GL_FRAMEBUFFER_DEFAULT as FBO attachment type
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=6d13ec7dc082aea9a8ce04dd8e045e77e5921d8a;p=mesa.git

mesa: return GL_FRAMEBUFFER_DEFAULT as FBO attachment type

If querying the default/window-system FBO's attachment type, return
GL_FRAMEBUFFER_DEFAULT (per the GL_ARB_framebuffer_object spec).

See http://bugs.freedesktop.org/show_bug.cgi?id=31947

NOTE: This is a candidate for the 7.9 branch.
