`TextLineBounds` property is not implemented

[agneszitte]

Current behavior

[All platforms] TextLineBounds property is not implemented https://docs.microsoft.com/en-us/uwp/api/windows.ui.xaml.textlinebounds

Expected behavior

TextLineBounds property is implemented on all platforms

How to reproduce it (as minimally and precisely as possible)

Try to use the TextLineBounds property on a Textblock.

Environment

Nuget Package: Uno.UI

Package Version(s): 2.0.532

Affected platform(s):

• [x] iOS
• [x] Android
• [x] WebAssembly
• [x] WebAssembly renderers for Xamarin.Forms
• [x] macOS
• [ ] Windows
• [ ] Build tasks
• [ ] Solution Templates

Visual Studio:

• [ ] 2017 (version: )
• [x] 2019 (version: 16.4.6)
• [ ] for Mac (version: )

Anything else we need to know?

Property really useful in some cases, like when using tight for numbers or text in all caps in order to center them inside an ellipse or a border for example. Most of the fonts don't have the same distance at the top or bottom from the baseline. It can be tricky sometimes to perfectly center everything vertically.

As a workaround for now you can use specific margins depending on the platforms to compensate for the distance.

@jeromelaban seeing that this issue is archived, is this wanted?

@agneszitte yes, depending on priority.
