Fix #1641. Excel allows explicit hiding of row after filter is applied, but PhpSpreadsheet automatically invokes showHideRows on all auto-filters, preventing users from doing the same. Change to invoke showHideRows only if it hasn't already been invoked, or if filter criteria have changed since it was last invoked. Autofilters read in from an existing spreadsheet are assumed to be already invoked. This is potentially a breaking change, probably a minor one. The conditions to set up 1641 are probably uncommon, but users who meet those conditions and are happy with the current behavior will see a break. The new behavior is closer to how Excel itself behaves. A new method `reevaluateAutoFilters` is added to `Spreadsheet`; this can be used to restore the old behavior if desired. The new method is added to the documentation, along with a description of how the situation described in 1641 is handled in Excel and PhpSpreadsheet. While examining Excel's behavior, it became evident that, although a filter is applied to an entire column, it is actually applied only to the rows that are populated when the filter is defined, as can be verified by examining the XML definition of the filter. When you re-apply the filter, rows that have been added since are considered. It would be useful to provide PhpSpreadsheet with a method to do the same. I have added, and documented, `setRangeToMaxRow` to `AutoFilter`. |

PHPExcel vs PhpSpreadsheet ?
PhpSpreadsheet is the next version of PHPExcel. It breaks compatibility to dramatically improve the code base quality (namespaces, PSR compliance, use of latest PHP language features, etc.).
Because all efforts have shifted to PhpSpreadsheet, PHPExcel will no longer be maintained. All contributions for PHPExcel, patches and new features, should target PhpSpreadsheet master branch.
Do you need to migrate? There is an automated tool for that.
