Here is my current ideal life cycle:

• Setup
• Game loop:
  • UpdateSetup
  • UpdateInput
  • Update
  • UpdateCleanup
  • Draw
  • DrawUI
• Cleanup

Setup: is where everything is put in place for the game loop.

UpdateSetup is meant to update stuff before user inputs are processed.
UpdateInput: should only be doing things that are related to user inputs. This step might not happen during the update phase if inputs are disabled.
Update: is for things that need to be updated regardless of user inputs. For example, animations can still happen even if inputs are disabled.
UpdateCleanup: gives the opportunity to cleanup variables before the next update phase.

Draw: is for drawing objects that belong in the game world.
DrawUI: is for drawing objects in screen space like UIs.

Cleanup: is called before something is destroyed. For example, in an in game map editor, this would be called when switching back to the game.

Features:

• Draw primitive shapes like lines, triangles, squares, circles.
• Outlines, filled. (SDF shape rendering?)
• Batching
• Push Pop states (Meta batching where you can reorder batches or even merge them?)
• Support per draw call matrix for translation, rotation, scale, etc.
