Python 3's signal.py API does not properly support custom signal handlers. An exception is created every frame because of this, which fills up the memory of the application.
Closes#873
This allows identifying, eg. the é button on French keyboard (which is at the location where 2 is on QWERTY)
This is not intended to be complete. One must still choose what to display depending on the label and the mapped button handle (if any).
Classes with virtual ref(), unref() and get_ref_count() methods, like RecorderBase, could not be returned by PT() from methods because they didn't inherit from ReferenceCount. However, classes do not need to inherit ReferenceCount to be able to be tracked by a PointerTo, and defining an abstract base class with pure virtual ref()/unref()/get_ref_count() is a way to avoid dual inheritance of ReferenceCount.
It's not "real" relative mouse like DGA, but it's good enough: it confines the cursor to the window and continues to provide relative mouse movement regardless of the position of the cursor in the window.
This gets relative mouse mode working under wayland, where cursor warping is not supported; see #746.
Made initialization ignore the setScrollBarWidth function
Respect the length/height of the scrollbar and only change the actual
width in the setScrollBarWidth function
Added a very basic unittest class for the scrolledFrame
Closes#864
If multiple ShaderMatSpec entries use the same state matrix, this should result in a reduction in the number of times that state matrix is fetched. This is especially so for arrays, which are now fetched once rather than once for every item.
This is the first step towards trying to solve #846.
There is an intermittent build failure and I suspect it's because the keys are too generic and are interned, and thus may have their refcount incremented or decremented by some other (background?) process.
The previous behavior was for unloadAnims() to remove the control effects from all animations, even when only one animation was passed in, which is unintuitive behavior.
Fixes#853
