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

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.
