[openbox] theme doc bugs

Hi,


window.active.grip.bg

Type: 	texture
Default: 	none
Parentrelative: 	------>no<-----

Specifies the background for the focused window's grips. The grips are
located at the left and right sides of the window's handle. ----->When
it is parentrelative<-----, then it uses the window.active.handle.bg
which is underneath it.

Same for window.inactive.grip.bg

Regards
