Subject: [PATCH 2/2] mesa-demos: Query display for EGL_MESA_screen_surface
|
|
extension before using it
|
|
|
|
This code makes heavy use of the EGL_MESA_screen_surface extension so
|
|
check the display to determine if it's supported by the underlying EGL
|
|
implementation. If it doesn't then bail.
