This is sort of an inverse of #5.
I like that BearLibTerminal preserves the virtual terminal row/column dimensions and just scales the screen bilinearly when I press alt+enter. I would like it to be able to do the same thing in windowed mode when the user resizes the window.
I guess the workaround might be to use a bitmap font, but it's odd that the windowed and fullscreen behaviors with regular text rendering are fundamentally different.
