Rotate horzy and verty etched concrete around its vertical axis
when it's placed. This only affects the direction of the stripes
on the top and bottom of the blocks. For example, a cross-beam
made of horzy concrete can now have the stripes on the top and
bottom of the beam in the same direction as the stripes on the
sides, or not, as desired, where before the top and bottom stripes
always ran east-west.
The inability to make solid white surfaces
has been a significant limitation to in-game
artistic expression for a while; this is an
inexpensive fix for that.
This makes mass-production of etched concrete
nodes a lot less tedious and more interesting.
There's now an incentive to manage multiple
separate styluses for larger projects.
When 3rd-party mods try to register extensions, don't
crash on trying to register in wrong namespace.
Keep registrations to original mod namespace for now,
as I'm not certain whether I actually made assumptions
about mod name in some logic.
Left to do:
- Adjust wet->pliant curing recipe (maybe use soaking
with ambient heat instead of cook/cool)
- Pliant->cured recipes/soaking.
- Stylus, pattern cycling recipes.
