Further sphere drawing routine optimization

[jakubg1]

Since commit https://github.com/jakubg1/OpenSMCE/commit/7dd78571ac261069264a134de272bf8aa55fc76f there is now a more optimized version of the sphere drawing routine. I want to optimize it further.

• Utilize SpriteBatch:
  • The following textures will have their SpriteBatch object:
  • All sphere textures (image field of each sphere definition object in config.json)
  • Sphere shadow image
  • Potentially sphere dimmer?
  • When a Sphere appears on the track, add a sprite to a corresponding batch and retrieve the ID.
  • When a Sphere leaves the track, "remove" the sprite by moving it to a specific position, as specified here.
  • Each draw, we want to update all sphere sprites to a new position.
  • I don't know in which class the batches will be stored yet. (Probably Map.lua)
  • Every specified time (one minute?) the batches will be emptied and all Spheres will again be re-added. This is to remove all pseudo-removed empty batch sprites.
• Since we can't color spheres one by one in sprite batches, the sphere dimming will be provided by overlaying a black circle over the sphere with an appropriate transparency.

Milestone removed due to some other optimization work done for now.

I don't think we need to complicate stuff that much while it's already running fast and smoothly. This requires much more work than it's really worth. Closed.
