* Ignore square-$-brackets prefix in format string
* Test for square-$-brackets prefix in format string issue fixed
* Fix for phpstan compliance
* Additional assert for checking number format of tested source cell
* Expand Chart Support for schemeClr and prstClr
Fix#2219. Address some, but not all, issues mentioned in #2863.
For Pie Charts, fill color is stored in XML as part of dPt node, which had been ignored by Reader/Xlsx/Chart. Add support for it, including when specified as schemeClr or prstClr rather than srgbClr. Add support for prstClr in other cases where schemeClr is supported.

File from https://www.rondebruin.nl/win/s2/win003.htm. I have been in conversation with the author, who has no objection to its use. I have not actually opened the file in Excel (at least not with macros enabled); I am using it merely to demonstrate that the ribbon data is read and written correctly. Test added; no source code changed. This should slightly increase coverage for Reader/Xlsx (moderate), Writer/Xlsx (slight), and Spreadsheet (substantial). Note that this file has no Ribbon Bin objects, so some coverage is still lacking.
No doubt some developers will complain that it should be the other way round, that datatpe should be modified to match the specified value; but then they should be using setValue() instead; the use of setValueExplicit() is explicit.
* Add Support to Chart/Axis and Gridlines for Shadow
Continuing the work from #2865. Support is added for Shadow properties for Axis and Gridlines, and Glow and SoftEdges are extended to Gridlines. Tests are added. Some chart tests are moved from Reader/Xlsx and Writer/Xlsx so that most chart tests are under a single directory.
This is a minor breaking change. Since the support for these properties was just added, it can't really affect much in userland. Some properties had been stored in the form which the XML requires them rather than as the user would enter them to Excel. So, for example, setting the Glow size to 10 points would have caused it to be stored internally as 127,000. This change will store the size internally as 10, obviously making the appropriate conversion when reading from or writing to XML. This makes unit tests much simpler, and I think this is also what a user would expect, especially considering the difficulties in keeping track of the trailing zeros.
* More Tests
Confirm value change between internal and xml.
* Still More Tests
Add a little more coverage, and use a neat trick suggested by @MarkBaker in the discussion of PR #2724 to greatly simplify MultiplierTest.
* Add Support to Chart/Axis for Glow/SoftEdges
Chart is very under-covered in unit tests. I was hoping to just add some tests and be done with it, but that just won't suffice - many code changes are required. Adding Glow properties for Axis turned out to be a real mixed bag - no support in Xlsx/Reader at all, support in Xlsx/Writer ... for the X-axis only. So we'll just inch forward in many stages.
This change does not address other Axis properties (Fill, Shadow, Line, LineStyle, and maybe others, and their sub-properties). On my to-do list.
GridLines, and maybe other Chart objects, also should support these properties. This change does not address those. On my to-do list.
No support is added for spreadsheet formats other than Xlsx.
* Refactoring
This should make the code easier to follow, and I hope it will also be extensible to other object types (e.g. GridLines).
* More Refactoring
Make scheme/srgb easier to handle.
* Fix Typo
In a very rarely used function.
Mostly new tests, some code annotations, some minor code changes:
- RichText clone logic is wrong
- TextElement doesn't have object properties, doesn't need clone
Continuing the work from #2828, #2841, #2846, and #2852. This is probably my last change in this area for a while.
Bubble charts can have bubbles of different sizes. Phpspreadsheet had not supported this. Openpyxl comes with sample code to generate such a chart. I was especially drawn to that solution because its namespace usage would have been unexpected before 2852. And it turned out to come with other surprises - use of absolute paths in the .rels files (PhpSpreadsheet expected only relative), use of a one-cell anchor to place the chart (PhpSpreadsheet expected two-cell anchor or absolute positioning), plaintext in the legend (Phpspreadsheet expected RichText), no cached values for chart data. Excel handles the file okay, and this PR makes sure PhpSpreadsheet does as well. This file is now Samples/Templates/32readwriteBubbleChart2, and is used for both generating a sample output file and in formal tests. A new sample in the 33* series demonstrates how to code these.
* Namespacing Part 3 - Charts
Charts still need some work, but they are now in good enough shape that the code that reads them can handle namespacing properly. Rather than a set of static routines, Reader/Xlsx/Chart needs to be changed to a regular object, with the relevant namespaces passed in the constructor. I am still looking for a test spreadsheet with non-standard namespacing for a full-blown test, but, in the meantime, the existing tests and samples will suffice. When I find a test case, I will certainly add it.
The resulting code is actually simpler than it had been because of the elimination of the need for a NamespacesMeta variable in all the function signatures. Because of that, enough errors disappeared from Phpstan that I decided to just finish that job - its baseline file now dips below 5,000 lines.
* Update Change Log
Need to document many chart changes.
