notcurses/include/ncpp/Selector.hh
Marek Habersack e429724287 [C++] API sync + some (breaking) changes
Added:

 * Plane: gradient (`ncplane_gradient`)
 * Plane: gradient_sized (`ncplane_gradient_sized`)
 * NotCurses: drop_planes (`ncplane_drop_planes`)
 * NcReel: constructor which takes `Plane&`
 * Visual: constructors which take `Plane const*`, `Plane&` and `Plane const&`)
 * ncpp_build: a nonsensical "demo" which exists purely to test whether
   the C++ builds and does absolutely nothing interesting.

Broke:
 * All exceptions throw temporary objects instead of allocated
   instances. Less typing in `catch` :P (and more conventional)
