this fixes tests that ended up comparing zero alpha to an unitialized alpha value
also improve reporting so that failing color comparison tests will print the color in hex

* specials: comment all parser cases
* specials: scan_graph: early-return if args is null
* specials: fix logic in scan_graph
* tests: add scan_graph parsing test
* specials: separate command parsing from graph parsing
this simplifies the implementation of graph parsing and makes it less ambiguous to parse graphs in contexts where commands are not expected
* specials: tweak comments in scan_graph
* tests: update for scan_command separation

* gradient, colours: use 24-bit colour depth internally on Wayland
our Colour type assumes this anyway; lower colour depth should be handled by display backends
* core: restore gradient color computation
this was mistakenly disabled when moving to a unified Colour representation
* core, gradient: use Colour type
* tests: gradient: always test hsv/hcl
colour computations no longer depend on the display backends we compile with, so these can be tested unconditionally now
* gradients, specials: use Color type
this makes specials now accept color names as well as hex codes, and removes all notions of color depth from gradient calculations

It's not quite clear to me what the intent was here, but I don't believe
this change was correct. We shouldn't block on callbacks within the main
loop.
This fixes #901.
