Detailed Description of the Pull Request / Additional comments

Scrolling jumpiness is caused by rounding errors. Instead of retrieving the current scrolling value from GetScrollOffset, which is already rounded in int, let the scrolling operation to operate on _scrollBar's Value directly (which uses double) in TermControl.cpp.

Validation Steps Performed

Testing scrolling on the following scenario manually:

  • nonscrollable terminal (e.g. the window is large enough to contain the current buffer).
  • scrolling to the topmost and bottom-most.
  • scrolling TUI apps such as nano and more in WSL.
  • after clearing the terminal, both in cmd and WSL.

has the same behavior between using touchscreen or precision trackpad and regular mouse wheel.
