Wez Furlong 1e32ccbd2f shaping: fix an issue where we'd lose combining marks like U+20d7
For a sequence like `e U+20d7` the intent is to render the `e` with
a vector arrow over the top.

This is typically implemented by fonts as an `e` followed by the
vector glyph (or vice versa), where either one of those may have
a zero advance so that the two elements are combined.

There were two problems here:

* During shaping we'd see the zero advance and assume that the entry
  was useless and skip it
* During rendering, if we didn't think it had any cell width, we'd
  not render it

Cursoring through that particular sequence can hide the vector
mark if the cursor is set to the default block cursor due to annoyances
in how the block cursor is rendered (it changes the fg color to match
the bg, but for elements outside where we think the cursor is, this
makes those elements invisible).
