Incorrect signature for GetPixelMapxv from OES_fixed_point

[castholm]

There appears to be a copy/paste error in OES_fixed_point, which states that GetPixelMapxv has a size parameter:

OpenGL-Registry/extensions/OES/OES_fixed_point.txt

Lines 128 to 129 in e5778b0

	void PixelMapx{enum map int size T* values);
	void GetPixelMapxv{enum map int size T* values);

(Note also that there's a missing comma between int size and T* values.)

But further down, it says that GetPixelMapxv is just the "x" version of GetPixelMap as defined in OpenGL 1.3:

OpenGL-Registry/extensions/OES/OES_fixed_point.txt

Lines 352 to 354 in e5778b0

	Revise to include 'x' suffix for GetClipPlane, GetLightm GetMaterial,
	GetTexEnv, GetTexGen, GetTexParameter, GetTexLevelParameter,
	GetPixelMap, and GetMap in Section 6.1.3.

GetPixelMap does not have a size parameter:

void GetPixelMap{ui us f}v( enum map, T data );

This error has snuck into gl.xml:

        <command>
            <proto>void <name>glGetPixelMapxv</name></proto>
            <param group="PixelMap"><ptype>GLenum</ptype> <name>map</name></param>
            <param><ptype>GLint</ptype> <name>size</name></param>
            <param len="size"><ptype>GLfixed</ptype> *<name>values</name></param>
        </command>

The extension specification and gl.xml should be updated to remove the size parameter.

Another problem: The extension specification says "Revise to include 'x' suffix on PixelStore, PixelTransfer, PixelMap, ConvolutionParameter" and lists void PixelMapx{enum map int size T* values) as a new procedure, but there's no PixelMap*, only PixelMap*v with a v suffix.

If you want to propose a PR to tweak the XML and extension spec that's fine. This all sounds reasonable if very dated.
