// A renderlevel is [Major bits 32..8]|[Minor bits 7..0] |

// Range [0x00..0xff] - Blend onto the frame buffer (before even opaque objects) |
|
// Range [0x0100..0xffff] - Opaque and nearly opaque objects |
|
// Range [0x010000..0xffffff] - For blending objects (typically sorted amongst each other) |
|
// The minor bits denote a slight difference in draw order. For example, a decal wants |
|
// to be drawn after the opaque object it is applied to, but hopefully not very long after. |
|
// The avatar gets a render priority of kDefRendMajorLevel,kAvatarRendMinorLevel. This puts |
|
// it in the group of normal opaque objects with no render dependencies, but with the maximum |
|
// permitted minor level. So it will be drawn after the opaque background, and the opaque background's |
|
// decals, but before the first thing with a render dependency on the background (e.g. plants). |
