From: Alan Webb <alan_webb@us.ibm.com>

  This change addresses two issues:

  [1] It adds a flag field to the blendface call which allows the
      caller to indicate whether or not the generated asset is
      temporary, and whether or not the asset being replaced should
      be explicitly retired fromt the memory cache. The decimal
      values correspond to:
      0 - Permanent asset, do not expire old asset
      1 - Permanent asset, expire old asset
      2 - Temporary asset, do not expire old asset
      3 - Temporary asset, expire old asset
      '3' corresponds to the default behavior seen today, and is
          the continued behavior of the non-blendface calls.
  [2] The dynamic texture routines are highly-asynchronous and can
      be scheduled simultaneously on a multi-core machine. The nature
      of the texture management interfaece is such that updates may
      be lost, and the nature of asynchornous operation means that
      they may be processed out of order. A lock has been added to
      ensure that updates are at least atomic. No attempt has been
      made to enforce ordering. The lock applies to the SceneObjectPart
      being updated and is held for the lifetime of the TextureEntry
      used to carry texture updates (the one instance carries all
      faces supported by the prim).

   Users of these services should remember that the dynamic texture
   call is asynchronous and control will be returned *before* the
   texture update has actually occurred. As a result, a isubsequent
   GetTexture call may not return the expected asset id. A script
   must wait for the corresponding TEXTURE_CHANGED event before
   retrieving any texture information.
