Filter examples (#1868)
* Allows filtering of examples

* For some reason, the ui designer ignored the courier font family so I manually inserted it into the .ui file

* Allows filtering by file content, too

* Respects dark mode (maybe?), fixes policy setting on code layout

* Prevents "run edited code" from showing unless the actual content changes

* Looks like black font is always best against highlight background

* Left test code in commit...

* Fix broken highlighting on PyQt6

* Address #133

* Better highlighting for both dark and light mode

* Minor refactoring/cleanup, uses combo box instead of checkbox

* Combo box below text edit to avoid clipping

Add almost all examples to ExampleApp (#1511)
* 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

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
