Add support for pseudo graphics apps with mouse support

[SiarheiKuchukBelitsoft]

1. Install Far Manager
2. Change config of Windows Terminal as following
   { "guid": "{b453ae62-4e3d-5e58-b989-0a998ec441b1}", "hidden": false, "name": "Far Manager", "commandline": "c:\\Program Files\\Far Manager\\Far.exe" }
3. Run Far Manager

Observe

1. Inconsistent sizes of vertical sized border elements
   

2. Now click and drag mouse by Window
   Observe text selection happens instead of passing data of mouse to app
   

Consider fixing font chars for those vertical borders and disabling mouse intervention for Far app.

Thanks!
