Are GLEW_VERSION_N_M values correct?

[devel-chm]

The current OpenGL::Modern bindings have implemented accessor XS routines to retrieve the values of the various GLEW state variables GLEW_\w+ (such as GLEW_VERSION_M_N where M,N might be 4,3). For my cygwin/win7 platform, I get the same results from our accessors as the glewinfo program that comes with the GLEW software distribution.

Reports by @wchristian to implement a test for these values seem to show results that are inconsistent with the advertised version of OpenGL of the test platform. However, the tests do not actually try the indicated functionality to determine if the GLEW_\w+ state values are actually correct. For example, from the GLEW usage documentation:

if (GLEW_ARB_vertex_program)
{
  /* It is safe to use the ARB_vertex_program extension here. */
  glGenProgramsARB(...);
}

and

if (GLEW_VERSION_1_3)
{
  /* Yay! OpenGL 1.3 is supported! */
}
