Subject: Check for existence of required version in Formatter
X-Git-Url: http://git.tdb.fi/?p=libs%2Fgl.git;a=commitdiff_plain;h=cfee1ea700d860db170fd1621f3716bc47b677f8

Check for existence of required version in Formatter

This way it doesn't depend on whether get_combined_glsl or get_stage_glsl
was called.
