Subject: Call the non-multisample version of storage if samples is zero
X-Git-Url: http://git.tdb.fi/?p=libs%2Fgl.git;a=commitdiff_plain;h=ff46db8939d1763eab5bbb4dca711d635fdb5f23

Call the non-multisample version of storage if samples is zero

OpenGL defines it like this.  Do the check in application code so it works
even if EXT_framebuffer_multisample is not supported.
