GetPointerv in GL4 ref is shown as unsupported in version 2.0-3.0

My understanding is that GetPointerv was initially introduced with OpenGL 1.1, removed with OpenGL 3.1 Core and readded with OpenGL 4.3 Core. However it is only displayed on the help page as supported in OpenGL 4.3+.

In addition, under Notes "It is available in the compatibility profile for all GL versions". I don't know whether this includes the OpenGL versions before the introductions of Core and Compat profile, however in case it does, this statement is also incorrect, as OpenGL 1.0 did not include GetPointerv.

Inspect the OpenGL 4 reference help page content for GetPointerv, including the supported-version listing and the Notes text. Verify the historical core and compatibility-profile availability, then correct the documentation so the displayed versions and note match that support history.
