xpand
xpand provides tools to zoom windows by a integer scale factor. It requires XComposite and XDamage extensions.
The targeted window is redirected offscreen and a new window is created with scaled dimensions. xpand reads the offscreen window pixmap and renders it at a scaled resolution in the new window, proxying input events to the backing window.
Cairo is used for rendering.
xpandwindow
xpandwindow is a shim to scale a given window using xpand.
TODO
- fix rough getopt use in xpandwindow shim
- use procedures defined in xpand.h to implement LD_PRELOAD hack to expand created windows for a program
- find some way to work around windows that listen directly to /dev/input/*
- simulate evdev events with X using intercepted procedure call to read?
- that sounds terrible
