Subject: [PATCH 1/1] macOS: Use Metal on >60 Hz displays

The problem with the occasional stutters related to SDL_WaitEvent() are still there, but on a 120 Hz display it's even worse to be stuck on 60 Hz. Metal is required for 120 Hz.

• Fixed how the ANSI FG color is adjusted to keep text legible on dark or bright backgrounds when BG color is unset.

• Fixed possible crash when there are ANSI escapes in the alt text of a preformatted block.

• Fixed tab/window titles containing ANSI escapes (escapes are removed).

+* macOS: Use Metal for drawing graphics if display refresh rate is higher than 60 Hz.

• Unix: Added a lagrange(1) manual page.
