More Culling

New Culling options:

• End Gateway culling - #167

Changes:

• Fixes some blocks not culling if texture has unused transparency - #154
• Fixed being able to see some culling in item frames when close - #163
• Fixed edge case where blocks with transparent texture prevents culling - #166
• Fixed item frames rendering at the wrong place when really far away
• Fixed powdered snow being completely see-through
• Ranges for item frame LOD & 3-face culling are also now in blocks. So its easier for people to use.
