Subject: Don't link program with the transform feature in constructor
X-Git-Url: http://git.tdb.fi/?a=commitdiff_plain;h=b37c25fb969b3fb6936ac456a07bd69c4c10cd00;p=libs%2Fgl.git

Don't link program with the transform feature in constructor

The transform feature produces calls to external functions, which need to
be added in a separate shader.  Trying to link in the constructor only
produces link errors.
