Issue 17 concerns adding a line for meshes in the definition table in
section 7.12. "Object bounding box units". In particular, an entry for
how to interpret the value 'objectBoundingBox' for the attribute
'gradientUnits'.

For meshes, the value 'objectBoundingBox' does not make a lot of sense.
The mesh patches are defined in terms of paths which use the current
user unit. Only the 'x' and 'y' attributes on the mesh element itself
could possibly use 'objectBoundingBox' and only in the case where the
mesh is being used as a paint server. (Referencing the bounding box of a
stand-alone mesh would be self-referencing.)

I propose that we do not allow the attribute 'gradientUnits' of meshes
and that coordinates in meshes are always interpreted as
'userSpaceOnUse'.
