Good point :-). But the data part in the X request is there for the
purpose, so it's possible to keep the 'base' request general purpose
and use different data for different gradients.

This was exactly the piece of code I had in mind :-). The dispatcher
has to do some work to fill the structures already, so I'd had expected
to see a single X request for all three. Anyway it's mainly a matter
of philosophy. I'd like to see the X protocol to remain lean and avoid
the mess that XKB extension is. Anyway I admit that I'm biased here...
Considered the type of work I'm personally doing, I'll try to oppose
the proliferation of wire protocol's requests as much as I can ;-).
