* Fix function-like macro arguments being expanded even when they were participating in token expansion or stringification
* Fix __has_include with comma or closing parenthesis in angle-quoted filename
* Don't issue warning if macro is redefined with identical definition
* Fixes for extraneous spaces being added to expansions
* Assorted refactoring
This should resolve#1638.
When a frame is dropped, the previous non-dropped frame is considered to be repeated, but the strip chart would compute new cached frame data for it, causing performance to be unusably slow at high frame rate data gathering even when most frames are skipped
This makes performance remotely usable in that situation
See #1466 - these classes are still part of panda3d.core as of 1.11, but they should really be imported from panda3d.net (they can be imported from either place in 1.11). A future release will remove them from panda3d.core entirely.
As workaround for https://gitlab.gnome.org/GNOME/gtk/-/merge_requests/2029, we manually create a GtkFlowBoxChild instance and attach the label to it and increase its reference count so it it not prematurely destroyed when removed from the GtkFlowBox, causing the UI to segfault.
Menus would only update properly if there was a strip chart open that would cause the PStatView to be updated
Calling `check_update()` in `new_collector()` doesn't work properly because the views haven't been updated there yet; calling `do_update()` there does work around it but I think the better fix is just to make sure we always update the view so that the `check_update()` (which is also called by `idle()`) works properly
This is more idiomatic, simplifies the code, makes it easier to port to eg. HPy later on, and makes it easier to use the limited ABI (where it can be optimized to a tail call) later on
A polyfill is provided for compatibility with Python versions 3.8 and 3.9
