Struct CellGrid 

pub struct CellGrid {
    pub cols: u16,
    pub rows: u16,
}

The character grid a pixel surface maps to.

Both the viewport (how many buffer lines and columns fit) and the start screen (what canvas to centre on) need this, and they used to compute it separately: resize divided height by line-height and subtracted a row, render subtracted a line-height and then divided. Same intent, two spellings, two places to get the status-row reservation wrong.

Pure and total — no GPU, no state — which is what makes the one piece of arithmetic in the GPU face that can actually be WRONG testable without a device. The 0.6 is glyphon’s monospace advance ratio for Family::Monospace: an estimate, and the honest reason the start screen centres approximately rather than exactly.

Fields
