Sorry I am replying to my own email, but all of my questions to bill

I agree that we need x/y/zticklabelobjects, in fact I already have
this in octplot under the name x/y/zticklabelhandle, This allows
fine-grained control over label properties. However the x/y/zticklabel
property should be kept IMHO for 2 reasons:
1. mlab compatibility
2. usability -- it is very convenient to set the labels using cells/string

OK, but the only subobjects which can inherit are the text objects --
line properties are determined by the lines in the plot and if the
"box" (be it a patch or axes object) inherits color as well we won't
be able to see the text
