Debug overlay is not readable when using scaling

[peacememories]

Hi, and thanks for developing this great little engine.

We're developing a game in GBA resolution and are using 160*144 pixels, with a scaling of 4, to get to 640 px in width.

This works great for the game, but it seems to also affect the debug menu, which means that most of it is completely unreadable. I've dug through the code a bit, and it seems the debug view does use a form of renderUnscaled which resets the width and height to its full 640px temporarily, but it seems this does not mean a higher resolution for the debug interface.

Are we doing something wrong here, or is this intended behavior? I think it would make sense to render the debug UI at higher resolutions even for low-res games, to keep the text fully readable.

Thanks for your time :)

That was fixed in #755
