Add gVim support for Windows

[mrtank]

I have a gVim 8.2 install from the original site of vim (https://ftp.nluug.nl/pub/vim/pc/gvim82.exe), and I have been able to use Fira Code with ligatures with some extra vimrc tinkering:

set renderoptions=type:directx
set guifont=Fira\ Code\ Regular:h10

But the following doesn't work: set guifont=JetBrains\ Mono\ Regular:h13

Dupe of issue #4 likely.

Doesn't draw the ligatures as we type (like fira code did), but at least after reloading the file, the ligatures show. (1.0.1 ttf)

Just use set guifont=JetBrains\ Mono:h13

[mrtank]

It doesn't matter if you add \ Regular or not. The problem is that it doesn't automatically draws the ligatures only for CTRL + L (refresh). FiraCode has that problem Sometimes tonsky/FiraCode#462 . But for JetBrains Mono it's constant.
