Rendering issues

I've found a few rendering issues/bugs:

First of, the sleeping mats stop being rendered when they are still in vision. I believe that it takes the rolled up version to "check" whether it still needs to be rendered. Here are some screenshots to show what I mean:

I was slowly looking up, and when the "rolled up position" of the sleeping mats is no longer in vision, the entire sleeping mat disappears.

 

The second issue is layering with ice blocks: The angle at which you look at ice blocks makes ice blocks that are behind other blocks look like they are in front. See the screenshots:

The issues with the sleeping mat are also common with sails, I think actually with any block that can have it's model "altered" by some form of action. I believe the easy way to fix this is to take the "large" variant of the model to calculate whether it should be rendered or not.
