                ICEsoft Public SVN Repository #29212 Mon May 28 11:00:10 MDT 2012 patrick.corless PDF-496 reworked Separation colour space to use any valid named colour before trying the alternative colour space. Also added a hook in the content parser to apply a tint value if specified in the Seperation colour space.

                ICEsoft Public SVN Repository #29216 Mon May 28 14:01:43 MDT 2012 patrick.corless PDF-496 removed transparency tint operand from content parser because of regressions. Replaced logic with adding alpha value to new colour creation which gives a mores consistent effect.

                Updated the TilingPattern class so that the bbox converted to users-space is calculated during to the init method and available to the content parser during parsing. We know only try to use a tilled paint if the bounds are larger the 1x1 pixel.

                Similar case, valuable for regression tests.
