-- These are the predefined button groups

-- "close" : name of the button, the images for this button are taken from the
-- theme variables titlebar_close_button_...
-- { align ... : attributes of all the buttons
-- select_state_focus : This function returns a short string used to describe
-- the state. In this case either "n" or "f" depending on
-- the focus state of the client. These strings can be
-- choosen freely but the< must match one of the idx fuekds
-- of the states below
-- { idx = "n" ... : This is the state of the button for the 'unfocussed'
-- (normal) state. The idx = "n" parameter connects this
-- button to the return value of the 'select_state_focus'
-- function. The img = "normal" parameter is used to
-- determine its image. In this case the iamge is taken from
-- the theme variable "titlebar_close_button_normal".
-- Finally the last parameter is the action for mouse
-- button 1
