This patch implements the Keying Screen node for the Realtime
Compositor. Draw data was introduced to the Movie Clip ID to allow
caching of the keying screen.

Depends on: #112480.

Cast gl_LocalInvocationIndex to int.

Cast `gl_LocalInvocationIndex` to `int`.

Use parenthesis around the test and cast CACHE_SIZE to int. Same thing for marker_color.

Can this me in the MovieClip_Runtime ?

I also don't really understand the comment or requirement. It is already not after id, and presumable things work just fine?

@Sergey I copied the comment from similar IDs, so didn't think it through. But I shall update all similar IDs in a cleanup commit. It should say after the AnimData member and reference the template type.

See IdDdtTemplate and DRW_drawdatalist_from_id to understand this requirement. This should also explain why it can't be part of MovieClip_Runtime.

Ah, I see. Seems a bit unintuitive, but is not related to this patch.
