~ forward port changes on the pull request #22 by @ambidot

Added positioning code based on material origin, size, and scale.
  Fixed mirrored vertices and mirrored BGRA pixels.
  Added DXT3 support.
  Fixed DXT decompression segfault due to sizeof (long).
  Fixed RGBA packing order.
  Enabled PKGV0008 support.
  Fixed detection of json "scene" string with uppercase characters.
  Fixed positioning of miscellaneous foreground objects.
