Blit a region from a screen draw context to a memory draw co


I’m new in Photon and I’m having a problem blitting draw contexts.

I’m trying to copy a region from the display (screen draw context) to a
memory draw context.

I can do it using PgReadScreen() to copy the screen image to a memory
context. The problem is that the cursor is also copied.

Does anyone know how to avoid to copy the cursor? Is this the best way
to do what I want?
