This picture shows that shapes now support draw modes also. While alpha will always be a slow process when drawing directly to video memory, the speed of Filled shapes has doubled.
Anyway here's the code for this simple effect
[pbcode]
CreateConvexShape 1,100,5
CreateConvexShape 2,80,5
MergeShape 2,1
Do
Cls 255
InkMode 1
BoxC 100,100,200,200,1,$ff00ff
InkMode 32+1
DrawShape 1,MouseX(),MouseY(),2
RotateShape 1,angle#,1
angle#=WrapAngle(angle#,1)
Sync
Loop
