LegendItem: fix docs & minor bugs (#1437)
* 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

Performance enhancement: use CUDA in ImageItem (#1466)
* 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

Scatter Plot Improvements (#1420)
* Added hovering demo to ScatterPlot example

* Use Qt's serialization for SymbolAtlas.symbolMap keys

Yields significant performance improvements when updating the scatter plot's options. See e.g. the plot hover example.

* Further optimized scatter plot picking

* Fix ScatterPlot example tool tip

* Clean up while I'm here

* Compatibility

* Some simple optimizations for ScatterPlotItem

Speedups for ScatterPlotSpeedTest.py:
~50% without pxMode
~ 0% pxMode with useCache
~30% pxMode without useCache

* ~3x speedup in scatter plot speed test with pxMode

* More optimization low-hanging fruit for the scatter plot

* Removed hover example to lazily pass tests

* Avoid segfault

* Re-add hover example to ScatterPlot.py

* Switch to id-based keying for scatter plot symbol atlas

- Use cases exist where serialization-based keying is a significant bottleneck, e.g. updating without atlas invalidation when a large variety pens or brushes are present.
- To avoid a performance hit, the onus is on the user to carefully reuse pen and brush objects.

* Optimized caching in scatter plot hovering example

* Fixed and optimized scatter plot hovering example

* Minor scatter plot optimization

* Cleanup

* Store hovered points in a set for the hovering example

* Keep a limited number symbol atlas entries around for future reuse

* Added a docstring note to remind the user to reuse QPen and QBrush objects for better performance

* Tidied up hovering example

* Typo

* Avoid unnecessary atlas rebuilds

* Refactored SymbolAtlas

* Efficient appending to SymbolAtlas

* SymbolAtlas rewrite

* Cleanup and profiling

* Add randomized brushes to speed test

* Add loc indexer to ScatterPlotItem

* Profile ScatterPlotItem.paint to identify bottlenecks

* Reuse targetRect to improve paint performance

* Readability improvements (opinionated)

* Only need to set x and y of targetRect

- w and h can stay set to 0 (not entirely sure why)
- this is a bit faster than setting all of x, y, w, h

* Minor renaming

* Strip off API changes and leave to another PR

* Renaming

* Compatibility

* Use drawPixmap(x, y, pm, sx, sy, sw, sh) signature to avoid needing to update QRectFs

* Use different drawing approaches for each Qt binding for performance reasons

* Fix a bug introduced two commits ago

Incidentally, I think there is a similar bug in the main branch currently.

* Minor performance and readability improvements

* Strip out source and target QRectF stuff

* Bring source and target QRectF stuff back in a less coupled way

* Leave deprecating getSpotOpts for another PR

* Compatibility fix

* Added docstrings and use SymbolAtlas__len__ where possible

* Fix export issue

* Add missing import

* Add deprecation warnings

* Avoid using deprecated methods

* Fix and cleanup max spot size measurements

* Make creation of style opts entries explicit

* Add hovering API to ScatterPlotItem

Fix TickSliderItem: Avoid ghost ticks | Improved customPlot.py code (#1459)
* Fix TickSliderItem: Avoid ghost ticks | Improved customPlot.py code

If `TickSliderItem.setTickValue` was called when a full repaint of the `TickSliderItem` was
not already scheduled, the tick was visible at the old and the new position. This could e.g. be seen
when using the autoscale button in the `customPlot.py` example.

Further, code from `customPlot.py` is improved to make use of `Tick.setVisible` instead of adding and
removing ticks based on their visibility.

TickSliderItem: allowRemove property added (#1442)
* TickSliderItem: allowRemove property added

Following #744, this PR suggests the addition of a property
`allowRemove` to `TickSliderItem` and therefore also to
`GradientEditorItem`. It sets the default of whether ticks can
be removed by the user and therefore contemplates `allowAdd`.

I would be interested in other opinions on this design decision,
as #744 suggests to reuse `allowAdd` for the prohibition of
tick removal.
I personally suggest this solution, since it does not change
the effect of the current API.

Fix #744

* customPlot.py: Added markers to example using TickSliderItem

* examples\GradientWidget.py: Demonstrate use of allowRemove

Fix ViewBox axis zoom in RectMode and examples/customPlot.py (#1443)
* Fix examples/customPlot.py: mouseDragEvent misses axis argument

Fixes #1277

* customPlot.py: Update methodolgy to disable menu

If there's an argument for this, we should use it

* customPlot.py: Show how to disable axis interaction

* Fix ViewBox: Moving axis in RectMode not implemented => use normal move mode

Grabbing an axis in RectMode leads to the zoom rectangle being displayed
in unreasonable positions. In this case, fall back to normal mode.

* customPlot.py: Only disable right-click zoom for demonstration

In cases where continuous zooming is not wished (e.g. in case of
complicated rebinning after zooming), this might come in handy
and there is no reason not to show it.

Add "left" and "right" step Modes (#1360)
* Add "lstep" and "rstep" step Modes

stepMode is currently either True or False. If it is True,
it requires the user to make len(x) = len(y)+1. This is
inconvenient because it makes it difficult to change the
stepMode on a given curve (just as one would change, e.g.,
its color).

This commit extends the current situation by introducing
two more step modes: "lstep" and "rstep", which do not require
passing an extra x value. In turn, this modes associate each
y value to either the left or the right boundary of the step.

For example, the "rstep" mode is handy when plotting "life"
digital signals in which x,y data pairs are appended as they
are read.

This commit does not modify the behaviour in case of stepMode=True

* Replace step mode names: lstep,rstep -> left,right

* Improve docs for stepMode

Reword docstring and add it to PlotDataItem class too

* Document left and right stepModes as added in v 0.12.0

TODO: confirm the exact version number to use here

* Add comments stress the need for "is True"

Some conditional statements in the code regarding stepMode are
done with "is True". This is actually required since other
possible values such as "left" also evaluate as true but should
not be caught.

* Deprecate boolean API for stepMode

Introduce stepMode="mid" as a replacement of stepMode=True,
but keeping full backwards compatibility with the old API.
Adapt docs, examples and tests accordingly.

* Raise ValueError on unsupported stepMode values

* Rename "mid" step mode to "center"

* Remove "added in 0.12.0" note

See https://github.com/pyqtgraph/pyqtgraph/pull/1360#discussion_r502746919

* Add deprecation warning when stepMode=True

Issue a DeprecationWarning if stepMode=True is being passed to the
constructor or setData() of PlotDataItem or PlotCurveItem.

Note: warnings module is imported locally so that it is esier to
remove once this check is no longer needed.

* Fix wrong syntax in last commit

Fix usage of "default" kwarg in dict.get()
