OK, thanks. Is cursor movement expensive on GNU/Linux? If not, I would do
something like below in term_show_mouse_face. That would just leave drawing
the highlighting where I've now put TODO (previously I manipulated write_glyphs
to use mouse_face_face_id but that was probably wrong). msdos.c uses:
IT_set_face (dpyinfo->mouse_face_face_id);
_farsetsel (_dos_ds);
while (nglyphs--)
{
_farnspokeb (offset, ScreenAttrib);
offset += 2;
}
if (screen_virtual_segment)
dosv_refresh_virtual_screen (start_offset, end_hpos - start_hpos);
Can I write directly to the screen like this in term.c? Or do I have to modify
the current glyph matrix somehow? (Which might be what xdisp.c does.)

save_x = curX;
save_y = curY;
pos_x = row->used[LEFT_MARGIN_AREA] + start_hpos
+ WINDOW_LEFT_EDGE_X (w);
pos_y = row->y + WINDOW_TOP_EDGE_Y (w);
cursor_to (pos_x, pos_y);
write_glyphs (row->glyphs[TEXT_AREA] + start_hpos, nglyphs);
cursor_to (save_x, save_y);
}
