Centralize all events and functions associated to the title bar in a single control TitleBar instead of code splitted between MainPage/TitleBar/HistoryList/Memory.
Use the standard title bar when high contrast is activated instead of the custom one.
Modify the color of the title when the window doesn't have focus
Fix the right padding of the title bar with high contrast
How changes were validated:
Manually tested with LtR and RtL languages
Manually tested with high contrast

Fixes#402 and #414
Divide by 4 the CPU usage of OverflowTextBlock when buttons are pressed very quickly.
Description of the changes:
Xaml-side:
OverflowTextBlock has some performance issues:
double scrollviewer: the listview was in a scrollviewer, while the control already containing one -> it breaks the virtualization of the listview and impacts on UI performance.
The listview used a StackPanel, this panel doesn't support virtualization of ListViewItems contrary to ItemsStackPanel
No ListView-specific features were used, an ItemsControl is more efficient and lighter.
refactor how we manage the visibility of the left/right buttons in OverflowTextBlock, the new version is more reactive and will not display the right arrow when not necessary (see GIF below).
remove the ItemContainerSelector ExpressionItemContainerStyle, not really used by OverflowTextBlock
remove UI glitches generated by ChangeView when users type fast (control partially hidden and scrolling issues, see the GIF below).
only modify the accessibility view when it's necessary
ViewModel-side:
stop fully refreshing ExpressionTokens in StandardCalculatorViewModel when a new command were sent, instead, use a IObservableVector to only send new tokens to the UI (in average only 1 or 2 UI items are refreshed while the full expression was refreshed before)
How changes were validated:
Manually
- Merge the 3 CalculationResultStyle(S|M|L) in App.xaml
- Only modify CalculationResult::*FontSize in Calculator.xaml instead of fully updating the style of the control.
- Create a new property MaxFontSize in order to be able to update it without being forced to fully update the Style (because m_startingFontSize was set in OnApplyTemplate)
- Modify how DisplayMargin is managed to prevent the textblock Margin to shift when we update its value (without fully updating the Style).
Description of the changes:
Hide the History button when in Programmer mode via VisualState
How changes were validated:
Open Standard mode
Switch to Programmer mode
Verify that the History button isn't visible
Fixes#326
* Calculator.xaml - Simple Readability Adjustments
Improved readability of the XAML document by inserting newline where they were missing and removed rextra newlines from others.
* Added comments and organized resources for superior readability
Using comments and grouping DataTemplates, Styles and other resources significantly increases the readability and discovery of resources.
