Subject: progs/egl: Fix screen surface demos.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=472a6019665094c18fc47624b343ddc8c90f102c;p=mesa.git

progs/egl: Fix screen surface demos.

Set the screen surface size to the mode size, as the spec requires the
screen surface size to be larger than the mode size.  Besides, bind the
API to OpenGL as they are written in it.
