Build 3.5.0.108 of xlsgen opens up new scenario combinations for converting files.

In essence, what's exposed is the in-memory conversion scenarios for PDF, ODF and XPS files. For instance XLS ==> ODF, XLSX ==> ODF, and so on. In other words, there is a better file conversion support in NewInMemory() OpenInMemory() and OpenFromMemory().

Build 3.5.0.107 of xlsgen fixes a formula parsing problem related to the percent operator being used prior or after unary or binary plus or minus. There could have a mismatch which would result in incorrect parsing and potential loss of formula.

Build 3.5.0.106 of xlsgen makes sure to copy sheet tab colors in Duplicate() scenarios.

Build 3.5.0.105 of xlsgen properly handles an internal en-masse hidden rows feature in XLSX files.

This feature is saved in Excel whenever the user selects all 1 million rows but a few ones, and chooses to delete them. This feature allows to avoid saving each and every of those deleted rows with a delete flag. Outside, the file size is kept very low.

Build 3.5.0.104 of xlsgen preserves a number of calculation mode settings from existing XLSX files.

These are :
- calcMode (manual/auto)
- fullCalcOnLoad (bool)
- iterate (bool)
- iterateCount (number)
- iterateDelta (number)
- fullPrecision (bool)
- calcCompleted (bool)
- calcOnSave (bool)
- concurrentCalc (bool)
- concurrentManualCount (number)
- forceFullCalc (bool)

Preserving the settings makes sure that updating existing files with xlsgen does not change the expected performance of the spreadsheet (speed and memory) at run-time in Excel.

Build 3.5.0.103 of xlsgen fixes and preserves an internal flag related to volatile functions in XLS and XLSX files (and their variants).

Build 3.5.0.102 of xlsgen fixes a problem related to how Excel 2010 saves form controls in XLSX files (and their variants).

Turns out that Excel 2010 saves alternates XML fragments in addition to VML drawings, which is how form controls were saved since Excel 2007 (and still are). xlsgen now ensures to preserve those alternate fragments as well.

Build 3.5.0.101 of xlsgen fixes two problems related to rendering chart data labels.

The first fixes how number formats for data labels get handled in some combinations from XLS files. The second one makes sure that data labels are rendered centered in stacked chart types.
