Anuj Verma a62fd640f3 [sdf -> bsdf] Added option to use squared distances. 
* src/sdf/ftbsdf.c (bsdf_is_edge): Modified the function
  to use distance map rather than the alpha values from
  the source image.

* src/sdf/ftbsdf.c (bsdf_approximate_edge): Only calculate
  approximate edges for edge pixels. Use `bsdf_is_edge' is
  to check for edge pixels. For non edge pixel assgn far
  away distances.

* src/sdf/ftbsdf.c (finalize_sdf): Handle distances in case
  of squared distances.
  And also use the macro `VECTOR_LENGTH_16D16' in the entire
  code to compute vector length. This takes care of squared
  distances.

* src/sdf/ftsdfcommon.c (VECTOR_LENGTH_16D16): Move the macro
  `VECTOR_LENGTH_16D16' from `ftsdf.c' to this file because
  it is also used by the `bsdf' renderer.

Anuj Verma f2553d89b2 [sdf,bsdf] Put common propertied and functions in one file. 
* src/sdf/ftsdfcommon.h: Added new file which contains
  common function, macros, properties for both `sdf' and
  `bsdf' renderer.

* src/sdf/ftsdf.c, src/sdf/ftsdf.h, src/sdf/ftbsdf.c:
  Remove common properties and include `ftsdfcommon.h'.

* src/sdf/rules.mk (SDF_DRV_H): Add the new `ftsdfcommon.h'
  file to include list.
