texelFetchOffset error

Prototypes for the gsampler2DMS and gsampler2DMSArray variants are missing, leaving the type and position of the referenced 'sample parameter' undefined.

In the glsl 4.60 spec these function doesn't seem to exist.
The line at the bottom about texelFetchOffset(gsampler2DMS, gsampler2DMSArray) being added in 1.50 seems like a copy paste error from texelFetch which has overloads for these.
