Subject: Support inline scenes within other scenes
X-Git-Url: http://git.tdb.fi/?a=commitdiff_plain;h=00dc5da40385d41c3a50c34c75353b257e814035;p=libs%2Fgl.git

Support inline scenes within other scenes

This is useful for creating scenes where transparent objects are rendered
after opaque ones, without the entire scene being Z-sorted.
