Graceful fallback among blitters #637
If we're in ASCII mode, no blitter except for NCBLIT_1x1 is going to
work. Whenever NCBLIT_DEFAULT is provided, select NCBLIT_1x1 if we're
in ASCII mode. Add NCVISUAL_OPTIONS_MAYDEGRADE and
NCPLOT_OPTIONS_MAYDEGRADE. Both serve to allow smooth degradation when a
blitter other than NCBLIT_DEFAULT has been provided. Closes #637.

Make calc_gradient_cell() static inline so our templated ncppplot
implementation can use it (ugh). When using NCBLIT_1x1 for plots in
ASCII mode, use space rather than full block, and invert colors.

Use NCBLIT_DEFAULT in the demo for the FPS plot.
