Wheeeee! Desktop icons can be selected by rubberbanding. You need Englightenment to do this, as so far it seems to be the only WM with support for the _WIN_DESKTOP_BUTTON_PROXY property. * gdesktop.c (click_proxy_filter): New event filter for button presses and releases on the root window. (click_proxy_button_press): New function to handle button presses on the desktop. (click_proxy_button_release): New function to handle button releases on the desktop. (click_proxy_motion): New function to handle rubberbanding motion on the desktop. (setup_xdnd_proxy): Flush the server after ungrabbing it. (find_click_proxy_window): Flush the server after ungrabbing it. (store_temp_selection): Stores the temporary selection to the master selection, or viceversa. This is needed for dynamic updating while the user rubberbands. (update_drag_selection): New function to update the selection while the user is rubberbanding on the desktop. (icon_is_in_area): New function to see if an icon is inside the rubberbanding area. * gdesktop-icon.h: Added fields for querying the icon and text position and size. * gdesktop-icon.c (desktop_icon_reshape): Set the position and size fields as computed for layout.
