I'd like to change the window/frame size of my XEmacs based on the current display resolution.
This is useful when I run my laptop either by itself or attached to a docking station with an external monitor. In either situation, I'd like Emacs to detect the primary screen resolution and adjust its main window frame size accordingly when I start it up.
The current display resolution is available using the following functions (both non-interactive).
(x-display-pixel-width)
(x-display-pixel-height)
