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

MAINT: Post 0.11.1 release, drop py2, qt4 (#1473)
* MAINT: Post 0.11.1 release, drop py2, qt4

This focuses on distribution, tests, and docs. This may not be comprehensive, but covers the cases I found by looking and a few greps

Noteably, this does not change any actual internal code yet, to avoid merge conflicts with pending PRs.

e6c8046320 Make the documentation reproducible
Whilst working on the Reproducible Builds effort [0] we noticed that pyqtgraph
could not be built reproducibly. This is because it generates copyright years
from the current build date and therefore will vary on when you build it.

This commit uses SOURCE_DATE_EPOCH [1] for the "current" build date.

This was originally filed in Debian as #963124 [2].

Date axis item (#1154)
* Add DateAxisItem

* Change style to camelCase

* Fix missing first tick for negative timestamps

* Add ms precision, auto skipping

Auto skipping allows a zoom level to skip ticks automatically if the
maximum number of ticks/pt is exceeded

* fixes suggested by @goetzc

* workaround for negative argument to utcfromtimestamp on windows

* attachToPlotItem method

* default date axis orientation

* Use new DateAxisItem in Plot Customization example

* attachToPlotItem bugfix

* examples of DateAxisItem

* modified description of customPlot example

* added descriptions to the new examples, reformatted their code, included the first one into utils.py

* typo

* Refactored code for setting axis items into new function

Replaces "DateAxisItem.attachToPlotItem"

* Fix string comparison with ==

* Doc: Slightly more text for DateAxisItem, small improvement for PlotItem

* Make PlotWidget.setAxisItems official

* Fix typo in docstring

* renamed an example

* merge bug fix

* Revert "merge bug fix"

This reverts commit 876b5a7cdb.

* Real bug fix

* support for dates upto -1e13..1e13

* Automatically limit DateAxisItem to a range from -1e12 to 1e12 years

Very large years (|y|>1e13) cause infinite loop, and since nobody
needs time 100 times larger than the age of the universe anyways,
this constrains it to 1e12.

Following suggestion by @axil:
https://github.com/pyqtgraph/pyqtgraph/pull/1154#issuecomment-612662168

* Also catch ValueErrors occuring on Linux before OverfloeErrors

While zooming out, before hitting OverflowErrors, utctimestamp
produces ValueErrors (at least on my Linux machine), so they
are also catched.

* Fix: Timestamp 0 corresponds to year 1970

For large years, x axis labels jump by 1970 years if it is not
accounted for timestamp 0 to be equal to year 1970.

* Fix: When zooming into extreme dates, OSError occurs

This commit catches the OSError like the other observed errors

* Disable stepping below years for dates outside *_REGULAR_TIMESTAMP

2 reasons: First: At least on my Linux machine, zooming into
those dates creates infinite loops. Second: Nobody needs
sub-year-precision for those extreme years anyways.

* Adapt zoom level sizes based on current font size and screen resolution

This is somewhat experimental. With this commit, no longer 60 px are
assumed as width for all zoom levels, but the current font and
display resolution are considered to calculate the width of ticks in
each zoom level. See the new function `updateZoomLevels` for
details.
Before calling this function, overridden functions `paint` and
`generateDrawSpecs` provide information over the current display
and font via `self.fontScaleFactor` and `self.fontMetrics`.

* Meaningful error meassage when adding axis to multiple PlotItems

As @axil noted in the DateAxisItem PR, currently users get a
segmentation fault when one tries to add an axis to multiple
PlotItems. This commit adds a meaningful RuntimeError message
for that case.

* setZoomLevelForDensity: Refactoring and calculating optimal spacing on the fly

* DateTimeAxis Fix: 1970 shows when zooming far out

* Refactoring: Make zoomLevels a customizable dict again

* updated the dateaxisitem example

* Fix: Get screen resolution in a way that also works for Qt 4

This is both a simplification in code and an improvement in backwards compatibility with Qt 4.

* DateAxisItem Fix: Also resolve time below 0.5 seconds

* unix line endings in examples

* DateTimeAxis Fix: For years < 1 and > 9999, stepping broke

Stepping was off by 1970 years for years < 1 and > 9999,
resulting in a gap in ticks visible when zooming out. Fixed by
subtracting the usual 1970 years.

* DateTimeAxis Fix: Zooming out too far causes infinite loop

Fixed by setting default limits to +/- 1e10 years. Should still
be enough.

* improved second dateaxisitem example

* 1..9999 years limit

* DateTimeAxis: Use OrderedDict to stay compatible with Python < 3-6

* DateAxisItem: Use font height to determine spacing for vertical axes

* window title

* added dateaxisitem.rst

* updated index.rst
