Subject: [PATCH 7/7] GLX: Add GLX_SGIX_fbconfig functions
|
|
|
|
Some older apps, e.g. games using version 3.0 or older of the glfw library
|
|
try to use the old GLX_SGIX_fbconfig extension functions if present instead
|
|
of the regular glXGetFBConfigs, glXGetFBConfigAttrib and glXCreateNewContext
|
|
functions.
|
|
|
|
This commit adds implementations of these to libglvnd's libGLX fixing e.g.
|
|
the "The Binding if Isaac: Rebirth" and "Crypt of the NecroDancer" games from
|
|
Steam failing with a "GLX: Failed to retrieve visual for GLXFBConfig" error.
|
|
|
|
Note this commit does not add implementations for
|
|
glXCreateGLXPixmapWithConfigSGIX and glXGetFBConfigFromVisualSGIX as these
|
|
cannot be simply mapped to non extension functions and in practice these
|
|
do not seem to be used.
