       This module implements objects that represent CSS primitive property values (as opposed to lists). It
       implements the DOM CSSPrimitiveValue, Rect, and RGBColor interfaces.

       If you need the constructor, it's below the object methods. Normally you would get an object via
       CSS::DOM::Style's "getPropertyCSSValue" method.

   CSSValueInterface
       cssText
           Returns a string representation of the attribute. Pass an argument to set it.

       cssValueType
           Returns "CSS::DOM::Value::CSS_PRIMITIVE_VALUE".

   CSSPrimitiveValueInterface
       primitiveType
           Returns one of the "CONSTANTS" listed below.

       getFloatValue
           Returns a number if the value is numeric.

       The rest have still to be implemented.

   RectInterface
       The  four  methods  "top", "right", "bottom" and "left" each return another value object representing the
       individual value.

   RGBColorInterface
       The four methods "red", "green", "blue" and "alpha" each return another  value  object  representing  the
       individual value.

   Constructor
       You probably don't need to call this, but here it is anyway:

         $val = new CSS::DOM::Value::Primitive:: %args;

       The hash-style arguments are as follows. Only "type" and "value" are required.

       type
           One of the constants listed below under "CONSTANTS"

       value
           The data stored inside the value object. The format expected depends on the type. See below.

       css CSS  code used for serialisation. This will make reading "cssText" faster at least until the value is
           modified.

       owner
           The style object that owns this value; if this is omitted, then the value  is  read-only.  The  value
           object holds a weak reference to the owner.

       property
           The  name  of  the  CSS property to which this value belongs. "cssText" uses this to determine how to
           parse text passed to it. This does not apply to the sub-values of colours, counters and rects, but it
           does apply to individual elements of a list value.

       index
           The index of this value within a list value (only applies to elements of a list, of course).

       format
           This is used by sub-values of colours and  rects.  It  determines  how  assignment  to  "cssText"  is
           handled. This uses the same syntax as the formats in CSS::DOM::PropertyParser.

       Here are the formats for the "value" argument, which depend on the type:

       CSS_UNKNOWN
           A string of CSS code.

       CSS_NUMBER, CSS_PERCENTAGE
           A simple scalar containing a number.

       Standard Dimensions
           Also a simple scalar containing a number.

           This  applies  to  "CSS_EMS",  "CSS_EXS", "CSS_PX", "CSS_CM", "CSS_MM", "CSS_IN", "CSS_PT", "CSS_PC",
           "CSS_DEG", "CSS_RAD", "CSS_GRAD", "CSS_MS", "CSS_S", "CSS_HZ" and "CSS_KHZ".

       CSS_DIMENSION
           An array ref: "[$number, $unit_text]"

       CSS_STRING
           A simple scalar containing a string (not a CSS string literal; i.e., no quotes or escapes).

       CSS_URI
           The URL (not a CSS literal)

       CSS_IDENT
           A string (no escapes)

       CSS_ATTR
           A string containing the name of the attribute.

       CSS_COUNTER
           An array ref: "[$name, $separator, $style]"

           $separator and $style may each be  "undef".  If  $separator  is  "undef",  the  object  represents  a
           "counter(...)". Otherwise it represents "counters(...)".

       CSS_RECT
           An array ref: "[$top, $right, $bottom, $left]"

           The  four  elements  are  either  CSSValue  objects  or  array  refs of arguments to be passed to the
           constructor. E.g.:

            [
                [type => CSS_PX, value => 20],
                [type => CSS_PERCENTAGE, value => 50],
                [type => CSS_PERCENTAGE, value => 50],
                [type => CSS_PX, value => 50],
            ]

           When these array refs are converted to objects, the "format" argument is supplied  automatically,  so
           you do not need to include it here.

       CSS_RGBCOLOR
           A  string beginning with '#', with no escapes (such as '#fff' or '#c0ffee'), a colour name (like red)
           or an array ref with three to four elements:

            [$r, $g, $b]
            [$r, $g, $b, $alpha]

           The elements are either CSSValue objects or array refs of argument lists, as with "CSS_RECT".
