Subject: Exclude EnvironMap effect itself when creating the map
X-Git-Url: http://git.tdb.fi/?p=libs%2Fgl.git;a=commitdiff_plain;h=00d3ccedefb1a5efb3d2d4625a2b68446703fbab

Exclude EnvironMap effect itself when creating the map

This avoids an unnecessary texture bind/unbind cycle if the EnvironmentMap
is contained within its own environment.
