This was originally added in d6fec89dc5 as
a doc-generation-only hack, but other tools such as stub generation may
need similar special cases, so it's now a env var check in the binding
generation directly.
It's not a check in every invocation because that *feels* slow (although
pybind11 itself likely does a lot more nasty string comparisons, hashmap
lookups and linked link traversal than that), so if such an env var was
defined while importing the module, the current() is then forever
broken, until interpreter restart.
Need that for configuring plugins -- originally thought I'd wait until
the class is reworked, but that isn't coming anytime soon given there's
insane pressure on other things, so I have to figure out a plan B.
The interface is the most barebones possible, exposing nothing that I'd
later plan to rename or remove. Just the least possible amount of APIs
to make it possible to configure plugins, and no custom type support yet
either -- if you need to write a vector, write it as a formatted string
instead, sorry.
To make it possible to test the APIs in isolation instead of through
the plugin interface, I added also a Configuration class. Also just the
least amount possible to cover the code with tests.
Phong has instancing and texture transformation so Flat should have that
too. Also fixed a bunch of doc omissions; there's no need to bind the
POSITION attribute the hard way either.
Everything needed to make a Python variant of the Text example. The
Oxygen.ttf font file is the same as in MagnumPlugins/FreeTypeFont/Test
in the magnum-plugins repository.
