* Since we're promoting everything, we reset the behaviour of
RDTreeWidget so that it's not doing anything different by default.
* RDTreeWidget's interface is a bit different, exposing some useful
things like a single selected item and so on.
* We also can't set columns in the Qt Creator UI anymore, so we set them
from code.
* We add our own custom item model to handle the cases we need. We can
also make a few assumptions and optimisations around things we can
safely assume like e.g. nodel columns won't really change after init.
* This lets us have full control over batching updates, which was the
main motivation, but it makes it easier to extend in future (e.g.
adding single per-item tags instead of the heavyweight Qt::UserRole
data elements).
* VAX can get confused by the QT_NAMESPACE macro, and if it thinks Qt
objects are inside a QT_NAMESPACE namespace then various things will
break but most commonly the ui objects inside that namespace won't be
picked up properly.
* See https://forums.wholetomato.com/forum/topic.asp?TOPIC_ID=12573
* We previously were only checking if all lookups had completed before
self-deleting, but we also need to make sure nothing externally is
still holding onto the dialog.
* This is only relevant for static qrenderdoc builds where the python
used isn't the system python, so it needs to locate its libs.
Otherwise the system libpython3.so and libs will be used.
* python3-dev for linking against python in qrenderdoc
* bison, autoconf, automake and libpcre3-dev for building the custom
SWIG used to generate bindings
* If it's called every write then it risks spamming the system with
signals and locking the UI thread with constant writes. Checking and
flushing output every 100ms is sufficient.
* In python globals aren't really global, they're just module-level
variables. So to find our _renderdoc_internal we have to potentailly
walk the stack if we're inside another module until we get to the
globals dict we set up.
* If a window (like the PythonShell) owned a context and only stopped it
on destruction, it would be destructed after the global shutdown
destroyed the interpreter.
