[Octave-bug-tracker] [bug #55895] __go_patch__ fails when NaN vertices exist

[Eddy]

Follow-up Comment #6, bug #55895 (project octave):

They are different bugs, but related because of the variable
`coplanar_last_idx`. Coplanar tester is the writer,
`opengl_renderer::draw_patch` is the reader. The decision to not include
unclosed patch in coplanar_last_idx will affect both sides.

I put the fix to both bugs in one patch (see attached file), otherwise the
patches will depends on each other to work correctly. I also moved the
coplanar test&partition code into a new function, because I think it is
complex enough and independent enough.

I tested the samples in comment #4, comment #3, comment #0, comment #0 in bug
#55751 <https://savannah.gnu.org/bugs/?55751#comment0> and a patch demo
<http://hg.savannah.gnu.org/hgweb/octave/diff/762eb2e33a7f/scripts/plot/draw/patch.m>.
No problem so far.

make check failed at bsxfun.cc-tst, so I can't run a full test.
