Many renderers do transparency in a great looking way,
that is not compatible with original LDraw...
Think of the LDraw format as a 3D format usable in many contexts.
It should not be tied to ONE implementation.
Suppose we could increase drawing speed by sorting lines/polygons,
wouldn't that be worth spending a META on?
Like we spend BFC META to increase speed.

Well, line type 2 is supposed to be colored 24.
Renderers could of course collect all differently colored lines
and display them last...

Fine with me. But please put a META next to them (before each line)
so we know what they are there for.
