We should use the perspective grilles in SL_windows_grilles.dmi

[Flaborized]

these grilles are in SL_windows_grilles.dmi (i did not draw them obv), I like them better than the not-in-perspective grilles we have, they'd need to be coded a bit to make them autoconnect correctly (like windows and doors do). would look Good and Aesthetically Consistent With The 3/4ths perspective
