Mode 2048 and CSI 14 t are size report control sequences which contain the text area size in pixels. The text area is defined to be the extents of the grid (rows and columns). Ghostty calculates the available size for the text area by setting the available padding, and then filling as much of the remaining space as possible. However, if there are remainder pixels these are still reported as part of the text area size. Pass the cell_size geometry through so that we can always report the correct value: columns * cell width and rows * cell height.
