Subject: egl: Wrap dri3 surface primitive around dri2 egl surface
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=0b3fc8f3054fe88d5368f6c747289cdeceb1c5d7;p=mesa.git

egl: Wrap dri3 surface primitive around dri2 egl surface

Originally dri3 egl surface was wrapped around _EGLSurface.

With next commit we'll add additional attributes, which will be checked
from generic code. Thus in order to access that we need to use
dri2_egl_surface.

The name of the latter is a misnomer - it should really be dri or
dri_common...

[Emil Velikov: commit message, squash the patches appropriately, add
relevant _eglInitSurface hunk to prevent build breakage]
