Subject: Move extension requirements from ProgramData to UniformBlock
X-Git-Url: http://git.tdb.fi/?p=libs%2Fgl.git;a=commitdiff_plain;h=9b2e1d2c6fe27574f10016b154dddad4f511996d

Move extension requirements from ProgramData to UniformBlock

ProgramData no longer manipulates GL directly, and it's used in places
like Renderer and Material.  This changes allows those things to be used
without shader support.
