we don't need at all, they can be disabled on all platforms.

2D array textures aren't supposed to filter between layers and the
computation used in the filtering code is meant to work with 3D
textures, not 2D array textures. The 2D array textures now use the
2D texture path instead of the 3D texture path to solve this issue.

There was some confusion between buffer mapping and size and offset
buffer binding arguments, which are distinct, but were represented
by the same Buffer class members. Added OffsetBindingPointer to solve
the issue and removed setOffset/setSize from the Buffer class, which
should not have existed in the first place (only the mapRange/unmap
functions should be allowed to modify these values, for now).

A few aspects of block declaration are improved upon here:
- Block definitions are computed and stored for later use.
  The data stored are the block member types and a map to
  convert from register offsets, based on the internal
  memory layout, to the std140 layout.
- Declaration of block members is possible. When a block
  member is declared prior to the entire block being
  declared, OutputASM::declareUniform() will first declare
  the whole block and return the index of the block member.
  If the block member is part of an already defined block,
  the function declares no new variables and returns the
  block member's register index.

This cl contains the necessary changes to make uniform buffers
usable in shaders. A few things to note:
- Uniform buffers can be set, but nothing will attempt to access
  them in this cl.
- While the 'index' of uniforms is expressed in terms of registers,
  uniform buffer 'index' is expressed in bytes in both PixelProgram
  and VertexProgram. This is necessary because of packing which can
  potentially put some variables in the middle of registers.
  Technically, std140 always packs variables in multiples of byte4,
  but other future layouts may not, so using bytes as the unit is
  more future proof.
- The above mentioned 'index' will have to be computed in OutputASM
  and extra operations will need to be added (to fetch a row from a
  row major matrix, for example).
