  Paste voxels in a box from the given buffer at a specific location.
  [code]dst_pos[/code] is the lowest corner of the box, and its size is determined by the size of [code]src_buffer[/code].
  [code]channels_mask[/code] is a bitmask where each bit tells which channels will be modified. Example: [code]1 << VoxelBuffer.CHANNEL_SDF[/code] only write SDF data. Use [code]0xff[/code] if you want them all.
- [code]src_mask_value[/code] For every pasted channel, if voxel data has this value, it will not be pasted. This is mostly useful when using blocky voxel types. Pass [code]0xffffffff[/code] to disable masking.
