WERETECH-8406

DC content is not persistent between onUpdate on real VA4 but it is persistent in simulator

In simulator (VA4) is DC content persistent between onUpdate calls and it is possible to draw only changes. On real VA4 is DC content cleared before every onUpdate and it is necessary to draw whole display content.

VA4: 3.80, SDK: 3.1.6

    To be absolutely clear, the original ticket (WERETECH-7828) was transferred to another team and was closed as by design. The new ticket WERETECH-8406 may result in more discussion and maybe a change in behavior. At the very least we should update the simulator to match the expected behavior. I've added notes to this effect, so hopefully we'll get some consistency either way.

    Thank you. Has current behavior some benefits? I see only disadvantages: more inconsistencies between devices, more work for developer to maintain, slower display update becouse on every onUpdate I must update everything, and then more power consumption (imho)
