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

* Compatibility

* Marshal pen and brush lists in setPen and setBrush

* Fixed platform dependent bug

Remove ViewBox.childGroup ItemClipsChildrenToShape flag (#1458)
The flag was set on ItemClipsChildrenToShape to solve the issue of #316
"A GraphicsItem object overlaps the ViewBox border line" at Luke Campagnola's
suggestion to solve further issues that @espdev had. Luke wisely
commented that this approach needs extensive testing.

We tested it. It broke PDF export in Orange. :)

A solution to #316 was merged in PR #321, which was refined from the discussion
in #316. I am not sure that, given rest of #321, the ItemClipsChildrenToShape
was really needed. Even without modifications to ChildGroup I did not
see any border problems (but I could replicate them in pre-#321 pyqtgraph).

Removing this flag fixes (and unneeded supporting code) fixes PDF export
regression in Orange while borders still seem a-OK.

arrayToPath: revert to old meaning of connect=ndarray parameter (#1461)
The i-th position of that array used to define if points (i) and (i+1)
were connected, but in master it defines whether points (i-1) and (i) are connected.
This commit reverts to (i) and (i+1) interpretation.

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.

Fixes for examples\customPlot.py (#1448)
* Fix examples\customPlot.py: Not object-oriented

Copy-paste error: I referenced a specific object instead of self. Fixed.

* Fix examples\customPlot.py: Allow calling setTicks more than once

This fixes a bug where TickSliderItem is expected to return ticks.keys() but while it returns ticks.items().
Also: Minor code correction.

* Fix examples\customPlot.py: Avoid scaling differences

Consider padding of TickSliderItem for link between ViewBox and ticks

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.

TickSliderItem: Use Tick.removeAllowed (#1441)
* Fix: TickSliderItem ignores Tick.removeAllowed

This prohibits removing ticks from a `TickSliderItem` if they were set to `tick.removeAllowed=False`.

Test code:
```python3
import pyqtgraph as pg
from pyqtgraph.Qt import QtCore
import numpy as np

app = pg.mkQApp()

class CustomWidget(pg.GraphicsView):
    def __init__(self, parent=None, *args, **kargs):
        pg.GraphicsView.__init__(self, parent, useOpenGL=False, background=None)
        self.item = pg.TickSliderItem(*args, **kargs)

        for pos in (0, 0.5, 1):
            tick = self.item.addTick(pos)
            tick.removeAllowed = False # Possibility 1

        # Possibility 2
        for tick, value in self.item.listTicks():
            tick.removeAllowed = False

        self.setCentralItem(self.item)
        self.setFixedHeight(31)

w = CustomWidget()
w.show()

app.exec_()
```

Previously, creating a `GradientEditorItem` lead to 34 executions
of `updateGradient`, with these improvements, only 2 are needed.
Further, removed duplicate code and used signals whenever possible.
