Subject: Add inline data items to the collection
X-Git-Url: http://git.tdb.fi/?a=commitdiff_plain;h=3ac3a51c623271da815c8ee60c484445871753bf;p=libs%2Fgl.git

Add inline data items to the collection

This simplifies the internals of various objects and does away with
the special keep() semantic of RefPtr.

Blend and DepthTest will be handled separately as part of rendering
state rework.
