* 7542 - baremetal: support cursor on a graphemeKartik Agaram2021-01-221-4/+9
| | | | | | | | | | | | | | | So far we've drawn a space implicitly at the cursor. Now I allow drawing an arbitrary grapheme when drawing the cursor. But the caller has to specify what to draw. (The alternative would be for layer 103 to track every single grapheme on screen along with its color and any other future attributes, just to be able to paint and unpaint the background for a single character.) I've modified existing helpers for drawing multiple graphemes to always clear the final cursor position after they finish drawing. That seems reasonable for terminal-like applications. Applications that need to control the screen in a more random-access manner will need to track the grapheme at the cursor for themselves.

It's not really manageable to make the fake screen pixel-oriented. Feels excessive to compare things pixel by pixel when we will mostly be writing text to screen. It'll also make expected screen assertions more difficult to manage. So I'm not sure how to make assertions about pixels for now. Instead we'll introduce fake screens at draw-grapheme.
