the Example App allows the user to choose a binding and a graphics
system to use to execute an example.
issue 1: setGraphicsSystem is obsolete and the method no longer exists.
thus selecting a graphics system causes an error.
issue 2: the choice of binding to use is passed as an extra command
line argument to be parsed by initExample. this is problematic for
examples that use argparse, such as VideoSpeedTest.py
issue 3: if the user has set PYQTGRAPH_QT_LIB, that takes precedence
over the choice made in the Example App.
this patch fixes the above 3 issues by setting PYQTGRAPH_QT_LIB in
the child process' environment and removing the old parsing of the
command line arguments
* feature TriangleROI
Added equilateral TriangleROI.
getArrayRegion is not working yet
* show off (and implicitly test) our new TriangleROI
* the PolyLineROI.getArrayRegion can be used by TriangleROI
refactor the actual logic to live on ROI
* refactors for readability
* variable names
* lint
* docstring type and purpose

* Fix ScatterPlotItem performance regression
* Add hover benchmark to ScatterPlotSpeedTest.py
* Removed a performance regression from GraphicsView
* Removed some tests failing due to the last commit
* LegendItem: fix spelling mistake
* LegendItem: remove unused curRow variable
* LegendItem: correct calculation of rowCount
Previously, rowCount would never be updated unless setColumnCount()
was called. This fixes that issue.
It also fixes that setColumnCount() rounded down (floored) the
number of rows, instead of providing an accurate number:
e.g. 4 items in 3 columns would yield rowCount=1, when it should be 2
* LegendItem: remove rowCount argument (not implemented)
Logic to actually use the rowCount argument was not implemented.
Users might expect rowCount to limit the number of rows to e.g. 1,
but that is not what the current code does (it only works with limiting
the number of columns).
Thus, we were exposing an unused/misleading parameter to users.
This can and should be reverted if the logic for limiting the number
of rows is added.
* LegendItem: add colCount docs
* test (LegendItem): remove unused curRow variable
* test (LegendItem): check increasing rowCount as add items
* Fixed logic in placement of items in legend with multiple columns
* Actual row count here should be 2, not 3

fix BufferError: cannot close exported pointers exist
for some reason, even though the ctypes object falls out of function
scope, it causes a lingering reference.
in any case, the use of ctypes is no longer necessary.
Don't change temporary files mid-way for Darwin
This fixes the CI issues on Darwin.
close the remote process on app shutdown.
* set environment variables before starting QApp
* fix-422
* Better support of hidpi
* Fix Typo in App-Name
* Remove fontScaleFactor bits
* Add documenation for hidpi displays
* Fix pg not defined

* fix: delete generated designerExample_*.py files
designerExample.py loads designerExample.ui directly
* remove unused examples/utils.py
* add almost all examples in folder
* use mkQApp and don't set style nor palette
not needed for an example and also avoids a PyQt6 6.0 refcount bug in
app.setStyle()
* bold interesting examples
* test_examples.py needs to know about Namespace too
* Revert "remove unused examples/utils.py"
This reverts commit 2eddead459.
* categorize examples lists in utils.py
skip tests that don't work for Qt6
add Qt6 and remove Qt4 from test_examples.py
update README.md
switch mouse tests to use QPointF
this eliminates all the special casing for different bindings
* Add NonUniformImage, example and tests.
* Use updated test-data tag
* Fix line ending, remove lut.setLevels keyword arguments call

* Add CLI args to video speed test for easier / automated benchmarking
* use a buffer-qimage so we can avoid allocing so much
this should improve performance under windows
* playing with numba
* oh, mins/maxes in the other order
* maybe put the cupy in here and see what happens
* pre-alloc for gpu and cpu
* handle possibility of not having cupy
* no numba in this branch
* organize imports
* name them after their use, not their expected device
* cupy.take does not support clip mode, so do it explicitly
* add CUDA option to the VideoSpeedTest
* rename private attr xp to _xp
* handle resizes at the last moment
* cupy is less accepting of lists as args
* or somehow range isn't allowed? what histogram is this?
* construct the array with python objects
* get the python value right away
* put LUT into cupy if needed
* docstring about cuda toolkit version
* better handling and display of missing cuda lib
* lint
* import need
* handle switching between cupy and numpy in a single ImageItem
* only use xp when necessary
we can now depend on numpy >= 1.17, which means __array_function__-implementing cupy can
seamlessly pass into numpy functions. the remaining uses of xp are for our functions which
need to allocate new data structures, an operation that has to be substrate-specific.
remove empty_cupy; just check if the import succeeded, instead.
* use an option to control use of cupy
* convert cupy.ceil array to int for easier mathing
* RawImageWidget gets to use the getCupy function now, too
* raise error to calm linters; rename for clarity
* Add Generated Template Files
* document things better
* cruft removal
* warnings to communicate when cupy is expected but somehow broken
* playing with settings to suss out timeout
* playing with more stuff to suss out timeout
* replace with empty list
* skip test_ExampleApp on linux+pyside2 only

this lets us support the various bindings w/o having to add binding
specific code.
it breaks PyQt4 support since PyQt4 template files are suffixed as
"_pyqt" rather than "_pyqt4"
QFont.setBold(True) calls QFont.setWeight(QFont.Weight.Bold)
in Qt 5, QFont.Weight.Bold == 75
in Qt 6, QFont.Weight.Bold == 700
in PySide6, QFont.setWeight() no longer accepts an integer value.
