Description

Environment

Windows build number: 19041.388
Windows Terminal version:1.1.2021.0

Actual behavior

Icons in powerline fonts are blurred in the Windows Terminal using 12 pt or lower, therefore ,they are hardly recognizable
The following sample is the Windows logo icon in Windows Terminal, Gnome Terminal on Ubuntu, and ConEmu:

~ 8_13_2020 12_16_06 AM (2)
Windows Terminal, font:3270NF, size:12pt - windows logo not recognizable
C__Windows 8_13_2020 12_29_29 AM
Gnome Terminal, font:UbuntuMono NF, size:12pt - windows logo recognizable
~ 8_13_2020 12_16_12 AM
ConEmu, font:3270NF, size:12pt - windows logo recognizable

I also tested other non-terminal software:
_Untitled - Notepad 8_13_2020 12_39_35 AM
notepad.exe, font:Anonymous pro NF,size:12pt - windows logo recognizable
OneNote for Windows 10 8_13_2020 12_47_00 AM
OneNote for W10 (100% resized), font:3270NF,size=12pt - windows logo recognizable

No source file, test, or entry point is named. Reproduce the issue in Windows Terminal 1.1.2021.0 with the listed powerline fonts at 12 pt or lower, compare the icon rendering with the provided terminal examples, and trace the terminal's font-rendering path. Done means powerline icons are recognizable at the reported sizes without regressing other text rendering.
