cropwindows

Description

Create cropped views of existing windows to display only part of them, typically to reclaim screen space from badly framed videos or programs and websites with terrible designs.

Usage

Look at the changes made to config.def.h: pass 1 to resizemouse to create a cropped window and to movemouse to move the underlying window in the crop.

{ ClkClientWin, MODKEY|ShiftMask, Button1, movemouse,   {.i = 1} },
{ ClkClientWin, MODKEY|ShiftMask, Button3, resizemouse, {.i = 1} },

Cropped windows are always in the floating state, use togglefloating (mod-shift-space by default) to uncrop and restore the underlying window to its original size and state.

Notes

tested with a limited set of clients and use-cases, some X11 events are probably not passed or handled correctly, report bugs if you see any,
known bug: if you crop a window at the same time another window is unmapped, there is a chance that dwm will lose control of the window you are cropping and your only option will be to kill it (this is a pain to fix properly),
improvements: investigate xextproto/shape for non-rectangular crops!
