329423f525 Use QTransform.rotateRadians when appropriate
In a few places in the library, we are doing the conversion from radians
to degrees just so we can call QTransform.rotate(), but there is a
QTransform.rotateRadians() method which would be more suitable, thus
making it so we do not have to handle the conversions ourselves

3ea92736b8 Do not use list comprehensions with any or all
python any and all are able to break early the moment they come across a
member of the iterable that meets the condition; but having a list
comprehension nested within breaks that ability to exit early, as the
list comprehension has to finish being constructed first before it can
be evaluated

314121192a Use math module for isfinite or isnan for scalars
Various places in the library attempt to check if scalars are finite
via numpy methods, which are intended to be used on numpy arrays.  Using
the math module equivalent functions on scalars is significantly faster.

In a few places, I also use numpy methods explicitly (np.all vs. all)

b0769f4be9 Use math.radians and math.degrees
Many places in the library were doing radian to degree conversion
via the manual calculation.  Doing timeit benchmarks on my system, I
am able to get a 4x speedup by using math.degrees or math.radians
instead

This commit replaces the use of np.sin/np.cos/np.tan uses throughout
the library with math.sin/math.cos/math.tan for scalar values

c4a1cf11a1 Use clip_array or clip_scalar instead of np.clip
Significant performance issues have been identified with np.clip
and thus clip_array was created to speed up the operation.  In addition
clip_scalar was created to clip a scalar value between two other values
this commit replaces many uses of np.clip from operating on scalars to
using clip_scalar instead

b0a3849960 Use math module methods for singular values
Using numpy methods that are intended for vectorized operations is
substantially slower than using the math module, so when feasible the
math module methods should be used.

allow gradient position to be configured on a histogram (#1729)
* NEW features for HistgramLUTItem

* gradientPosition=('left', 'right')
* only paint if item is visible (is faster)
* link hisogram to other histograms

* fixes to be able to merge

 * drop linkHistogram (rgba needs to be better integrated)
 * make sure defaults to same as current behavior
 * draw connecting lines correctly on each side
 * add example use

Protect makeARGB with tests and benchmarks (#1697)
* update to working

* cupy tests, too

* doubling up and down

* add more realism to the benchmarks

* name to reflect scale

* use different numbers to mean different numbers

(that sure does sound tautological)

* more sensible: order, error

* thorough check of lots of makeARGB arg combos

* docstring for tool usage

* no print needed

* better error messages

* test makeARGB using cupy, too

* skip without cupy available

* switch from conda to venv

* skip cupy runs when not available

* use endian-proof makeARGB shim in tests

* generate the asv conf to suit the system

* document running asv

* comments for future matrix goals

* put all makeARGB tests together; name for clarity

* subprocess.check_output is standard for all supported pythons

* better handle lack of git version

* use makeARGB shim

* small fixes and improvements

10c1e83cd7 Expose the clickable property of PlotDataItem. (#519)
* Fix the `clickable` property of `PlotDataItem`.

Currently if you attempt to set the `clickable` property of a PlotDataItem,
this property is silently ignored. The expected behavior is to set the
`clickable` property of the underlying PlotCurveItem.

* Use setCurvesClickable and curvesClickable instead

* curve is singular

2aed5c36d5 no need to reconstruct PyQt6 enums
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()
