%Center of Alpha Crucis is 90 units across and 12 units up
%Center of Gamma Crucis is 90 units across and 48 units up
%Pivot of Beta Crucis-Delta Crucis pair is 90 units across and 36 units up
%Axis joining Beta Crucis and Delta Crucis is rotated about the pivot, 82 degrees clockwise from the vertical
%Center of Beta Crucis is 14 units left (along axis) from pivot
%Center of Delta Crucis is 12 units right (along axis) from pivot
%Horizontal span of Alpha Crucis is 7 units
%Horizontal span of Beta Crucis is 6 units
%Horizontal span of Gamma Crucis is 6 units
%Horizontal span of Delta Crucis is 5 units
%Width of white border around each star is 1/2 unit
