[E-devel] RFC - New elm_entry function (rev: 65169)

[Tom H. <tom...@pa...>]

Hey all,

I added elm_entry_textblock_get so people will be able to do more 
low-level manipulations on the textblock object of the entry.

I explained the implications in the doc and also explained there that it 
should be use mostly for querying, but editing is also allowed as long 
as a couple of precautions are taken, and all the changes are followed 
by a call to elm_entry_calc_force.

As an additional warning to the nature of this function, I made it 
return a const textblock object (although, as I said editing is allowed).

What do you think? Should I keep the const? Remove it? Do anything else 
to make sure users of the API understand how it should be used?

Thanks,
Tom.
