Looking at the 1.0.1 specifications, paragraph 14.3.2, i see the following
const VGubyte * vgGetString(VGStringID name)
"If name is VG_VERSION, the version number of the specification implemented by the renderer is returned as a string in the form major_number.minor_number.
For this specification, '1.0' is returned."
Is it ok, or the returned string must be '1.0.1' ?
