Need to repeat last primitive after an ALIGN when sending CONT #4

Closed enjoy-digital closed 8 years ago

enjoy-digital commented 8 years ago

After ALIGN, when we are sending CONT, we need to repeat the last primitive before sending the next CONT.

Currently we are doing this: PRIM-PRIM-CONT-CONT-ALIGN-ALIGN-CONT-CONT-CONT...

and should do this: PRIM-PRIM-CONT-CONT-ALIGN-ALIGN-PRIM-PRIM-CONT-CONT....
