In the book, I've got an example where a gradient_sized() is replacing an ncplane_set_base(). Despite having CELL_ALPHA_BLEND, we're opaque, because gradient operations aren't preserving the alpha as promised.

Gradients: set alpha, better prechecks #389
c87a9ed 
Gradients can't use palette-indexed color, so don't allow it
in either the foreground or background of any channels. All
channels must have the same alpha setting, which will be matched
in the gradient. #389
