i think that's missing lots of data, and background.

looking at this, my guess is that this is for client-side decorations. but then
you are missing lots of data.

1. for wm window menu, not just x,y but also the rectangle withint he client
window that triggered the action should be supplied. this allows the menu to be
aligned right below the button that triggered it. nice and cleanly. without
this info the menu has no choice but to appear where the mouse is which may be
anywhere inside the button/widget that was clicked

2. button action gives no hint as to what the action might be. example - we
double-clikc the titlebar. in some wm's this shades/unshades the window. in
others it maximizes/unmaximizes. the info here provides no information that
would indicate to the wm that we double-clicked the titlebar as titlebar may be
along the left side of the window or along the bottom. no idea.
