           Summary: glGetActiveUniform returns size in wrong units
           Product: Mesa
           Version: unspecified
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Mesa core
        AssignedTo: mesa3d-dev@lists.sourceforge.net
        ReportedBy: bmerry@gmail.com


Page 81 of the the OpenGL 2.1 spec states "the value in size is in units of the
type returned in type". Mesa 7.0.2, however, returns a count of scalars. I will
attach a test program which demonstrates this: it queries a 4x4 matrix and
receives a size of 16 instead of 1.

I haven't written a test for it, but eye-balling the code for glGetActiveAttrib
makes me suspect that the same bug is present there.
