commit b55a0dd2406f4b360295bc20ec303757112906f1

    Remove texture layout endian-ness check for Moz2D.
    
    This resolves #986.
    
    This removes endian-based inversion of texture layout aliases when
    represented as uint32. This inversion was incorrect and would cause
    unknown texture formats as a result on big-endian machines (PPC64).
