PyQt6 can serialize / deserialize enums and flags w/o us manually
casting them to int.
In PyQt6 6.0, it was okay to pass the already deserialized flag
back to the class constructor.
In PyQt6 6.1, the flags MouseButtons and KeyboardModifiers have
been renamed to MouseButton and KeyboardModifier respectively.
skipping the reconstruction allows it to work on both PyQt6 6.0 and 6.1.
note that this was already done in deserialize_mouse_event()
the "offset" argument passed into rescaleData() is typically an element
of an ndarray, i.e. it comes from the lower bound value of the "levels"
ndarray. as such, arithmetic operations on it can overflow.
this triggers a runtime warning in the test suite.
the workaround is to convert it to a Python (integer) scalar.
* ROI.py, getArrayRegion: Fix return mapped coordinates
The *getArrayRegion* method is defined as returning a tuple of the points
in the selected region and the mapped coordinates if the
*returnMappedCoords* keyword argument is set to True in the parent class
*ROI*.
In the *EllipseROI* class, *getArrayRegion* was overriden, however it
ignores the *returnMappedCoords* keyword argument, leading to unintended
bugs because of the change in interface between the parent class and
the subclass.
This patch fixes the above bug.
If *returnMappedCoords* is set to False, then only *arr* containing the
array region is returned. If *returnMappedCoords* is set to True, a
tuple of the array region and the mapped coordinates is returned.
NB: At the time of this commit, the same bug is present in several classes
extending *ROI*. This commit only fixes the issue for the *EllipseROI* class.

* implement rescaleData_blocked
clip limits should be int if data is int
* add test for rescaleData_blocked
* dispatch to different versions depending on numpy or cupy
* make rescaleData() the only entry-point
* Initial implementation of ColorBarItem
* initial commit
* fixed missing indent
* docstring extension and corrections
* Converted example to match others / run as part of tests
* load local color maps instead of importing from colorcet
* clean up window creation code
* horizontal color bar and clean-up
* switched to mkQApp initialization
* cleaned up some comments
random.normal() generates as float64 and gets converted to a smaller
dtype. generating all the needed data in a single call thus uses a lot
more memory than is necessary.
this changes it such that smaller chunks are generated.
data clipping is also changed to be in-place.
the gaussian filtering which gave the video a washed-out look is also
removed. this also contributed to data generation time.
* allowed style updates to once again update the style of curve and scatter plot, added tests
* tests interleave assign and assert to guard against delayed assignment
