TYPE0 Force LOD
=========

type 0	C0.FFFF.00 PP.000.iii
	Loads image [i] setting Min-Level [P].  All flags [F] are acceptable.
	Functionally similiar to type 2, except it always sets the LOD.
	In addition, if "joy2 detail edit" is activated, the first instance of an image [i] sets the LOD and shift for all subsequent instances.  See below for more details.

TYPE1 - DETAIL
=====================

type 1	C0.FFFF.01 .PP.ooo.iii
	Level of detail image shifting.  Replaces (Clamped at value P) base image [i] with overlay image [o] when within LOD range.  All flags apply.
	Command requires two image IDs to function or is otherwise ignored.
	Note: technically the "base" and "overlay" are actually the other way around, but this describes the actual behaviour.
	P is of the bit format (0.8) and so has a range of (0.0 - 0.99609375)

// **********************************
// Sept2015 Found the little bugger! 
// Depot fails because its mixing CI with I. CI limits TMEM to 2048 (256 words) AND CI cannot be combined with any other type.
// Depot tries to combine types and also Overrun TMEM (last TMEM offset is 382 words, this overwrites the TLUT0 at address 257!
// IF Depot used TLUT15 at address 496 then 'Maybe' it would work so long as base was also 4bitCI using TLUT14
// If Depot used 4bitI detail (no reason for it being CI anyway) then it should work.

OK, so Grid uses a 4Bit I texture for detail and a 16bit rgba texture, both 32x32. 512+(2048+512+128+32+8) = 3,240 
This works because nether texture is CI and all tiles fit within 4096 bytes.

So, what we need to do is find out if there are any other detail maps in PD.













TYPE2 Normal LOD
===============

type 2	C0.FC00.02 00000.iii
	Loads image [i].  Only mirror, clamp, and offset flags are read.
	Most common image loading type.  Sets up to 7 tiles of diminishing size depending on proportions.
	Additionally, if "joy2 detail edit" is activated and LOD data has been saved for this image, the image will be applied at the specified level similiar to a type 0 command.  See below for more details.
