The "DRM_SURFACELESS" EGL platform was invented when we were adding the wayland backend to Clutter but in the end we added a dedicated backend instead of extending the EGL backend so actually the platform name isn't used.

# update, then increment REVISION (`C:R:A' becomes `C:r+1:A').
|
|
#
|
|
# 3. If any interfaces have been added, removed, or changed since the

|
# last update, increment CURRENT, and set REVISION to 0.

# 4. If any interfaces have been added since the last public release,
