Nick prefers error handling based on exceptions in all cases, while I
prefer to save exception handling for truly exceptional situations -
function parameter validation and class constructor. However, there's no
need to not support both approaches, to be chosen at the discretion of
the developer.
NCPP follows RAII and all classes throw exceptions from their
constructors in case they cannot initialize properly. Likewise,
functions taking pointers that are required validate them and throw
exceptions whenever the requirement isn't met.
This commit goes one step further in that it enables optional validation
of notcurses function return values and throwing an
exception (`ncpp::call_error`) should the function signal an error. This
is disabled by default but it can be enabled by defining the
`NCPP_EXCEPTIONS_PLEASE` macro (preferably on the command line or
before *each* inclusion of any NCPP headers).
Out of necessity, this breaks the ABI (plus I found a handful of minor
issues in the code), but I think it's worth having this support in
place.
At various places in rendering and rasterizing, we advance two
columns upon encountering a wide glyph. When dealing with a
single plane, this is always correct, because we're always
hitting the first column of the multicolumn glyph. Once multiple
planes are brought into play, though, we can very much hit the
second column of said glyph, in which case we mustn't advance
two columns, but only one. Resolves#474 by way of #475. w00t!

Tighten up interval arithmetic. Render the plot immediately upon
creation so that the labels are visible. Properly perform domain
detection on miny by initializing it to 2^64-1. Handle plotting
when miny > maxy, as it now will be upon creation when using
domain detection (#448). Add spaces as the first element of each
glyph cycle (#445).
