(v13) Thread synchronization

This page applies to Harlequin v13.1r0 and later; and to Harlequin Core but not Harlequin MultiRIP.

Synchronization between the host application calling thread and the thread that is running the RIP simplifies the host application code. This is because the host application does not have to worry about callbacks on the monitor or raster functions happening asynchronously; they happen only when the host application has called one of the SwLe functions and is blocked awaiting the result.
