A terminal renders a single glyph in a grid. That’s it. This stems from the days from before - when there was no graphics instruction to render anything different, and link speeds could be, on bad days, slower than typing speeds.
Terminal rendering evolved to include ANSI instruction to manipulate the rendering-color, grid position, etc.
However, at its core, is this limitation…a glyph in a grid…and this limitation is due to how slow terminals are.
Terminals originally operated at a serial baud rate where one could nearly type faster than the transmission speed.
X windows…was designed…to not have these limits.
Terminal emulation is handy, but … it is limited. By definition retro. If a terminal doesn’t work…move on…and make something that does :)
