Update ruby-mini-magick to 3.5.0.

No official changes are available, but various bugfixes and document updates.
Note update of graphics/ruby-mini-magick package to 3.5.0.
Update ruby-oily_png to 1.1.0.

* Bilinear resampling in C.
* Removed debugging printf.
* Set bounds correctly, add tests.
* Store pixels in uint32_t instead of long.  Saves space and works
  on 32-bit systems
* Bump chunky_png dependency to 1.2.7.
Note update of graphics/ruby-oily_png package to 1.1.0.
Update ruby-coffee-script-source to 1.6.1.

1.6.1 – March 5, 2013

* First release of source maps. Pass the --map flag to the compiler, and off
  you go. Direct all your thanks over to Jason Walton.
* Fixed a 1.5.0 regression with multiple implicit calls against an indented
  implicit object. Combinations of implicit function calls and implicit
  objects should generally be parsed better now — but it still isn't good
  style to nest them too heavily.
* .coffee.md is now also supported as a Literate CoffeeScript file extension,
  for existing tooling. .litcoffee remains the canonical one.
* Several minor fixes surrounding member properties, bound methods and super
  in class declarations.

1.5.0 – Feb 25, 2013

* First release of Literate CoffeeScript.
* The CoffeeScript REPL is now based on the Node.js REPL, and should work
  better and more familiarly.
* Returning explicit values from constructors is now forbidden. If you want to
  return an arbitrary value, use a function, not a constructor.
* You can now loop over an array backwards, without having to manually deal
  with the indexes: for item in list by -1
* Source locations are now preserved in the CoffeeScript AST, although source
  maps are not yet being emitted.
Note update of lang/ruby-coffee-script-source package to 1.6.1.
Add ruby-narray package version 0.6.0.8.

* NArray properties:

  + Fast and easy calculation for large numerical array.
  + Accepting Elements:
    8,16,32 bit integer, single/double float/complex, Ruby Object.
  + Easy extraction/substitution of array subset,
    using assignment with number, range, array index.
  + Operator: +,-,*,/,%,**, etc.
  + FFTW version 2 or 3 is separately supported.
  + NImage: Image viewer class.
  + Ruby/PGPLOT: Graphics library interface (separately distributed)
     X-Y Graph, Histogram, Contour map, Image map, etc.

* NArray is similar to:

  + Python/NumPy, Perl/PDL, Yorick, IDL
Add and enable ruby-narray.
Note addition of math/ruby-narray package version 0.6.0.8.
