Texture related bugs

[TrademarkTM]

These are simply problems with the texture of the maps.

• Double chests are not doubled.

• Command blocks have a very weird texture.

• Lava is greyish. Water has a normal texture.

• Pistons become 'purple' for an instant when activating them.

• Shulker boxes have no texture (the same as the piston being activated).

• When closed from the bottom part, the door does not update the upper part.

Just addressing these issues here, not very important.
Thanks again!

Those are some interesting bugs, especially the last one. I wonder how that came to be...

Fixed the lava. https://puu.sh/BCPFI/ad4fa300c9.png

EDIT

Shulker boxes and command blocks seem to render fine, so I'm not touching that.

Double-chest is a tricky bit because block rendering is meant more per block, not for multiblock. Workaround is rendering each half as a separate block.

Door updating I don't really know, I would think the underlying state information was correct. It's a little strange...

Pistons can maybe be fixed, of course having smooth motion is a no.

@bergerkiller double-chests are doable, at least in newer versions, unsure in older versions. They have block data that indicates whether they are the left half type=right, the right half type=left, or just a single chest type=single

Pistons still disappear for a moment when extending or retracting, and the sticky piston texture is wrong when retracted (correct when extended)
