You know there is no such thing, right?

First of all, this is clearly wrong.  GL_MAX_TEXTURE_SIZE must be at least 2048
(or is it higher these days?), and there is no 2048x multisampling.  I have
submitted a bug to the Khronos public bugzilla for this issue:

https://www.khronos.org/bugzilla/show_bug.cgi?id=1419

> Open GL.4 clearly states:
> An INVALID_VALUE error is generated if samples is zero.

Second of all, if the man page ever disagrees with the spec, the spec is
CORRECT and the man page is WRONG.  Period.  Khronos reviews and votes on the
specifications, but the man pages do not receive the same level of scrutiny. 
They are also written primarily by Graham Sellers on a volunteer basis.

In the future, if you find a case where the man page disagrees with the spec,
please submit a Khronos bug and CC me on that bug.

> The fix is wrong, the defect needs to be reopen.
