Reinterpreting the grass side as a mask instead of a texture
causes some really ugly artifacts with texture packs designed for
legacy textures and not overriding this.
Renaming the texture prevents the collision, and creates a sane
fallback for texture packs that don't have an override.
- Intermediate number of stages.
- No dizzying rotation.
- Still has a blank first stage for emergency hand-dig.
- More reminiscent of isometric cube motif.
- Lines coming from center make it more "crack-like".
These are based on the nodecore "honeycomb", so they should at
least thematically match the other textures somewhat, even if
they're not super-attractive.
Rename it to "lode" so that its relationship with the more familiar
iron element is less direct, to maintain a higher baseline level of
suspension of disbelief.
Also restructure the way ores work in general, especially with
respect to normal stone. Natural ore deposits are stone with a
texture overlaid. Cobbled ore is the same ore "stain" texture with
alpha stripped and cobbles drawn over it. Normal cobble is now
basically what "gravel ore" would look like. This should allow
us to get a more consistent ore appearance with fewer textues.
