Sort:
1. User agent declarations
   1. Default value
   2. Specified in default style sheet (which I am going to supply)
2. User normal declarations
   1. Specified in user-supplied style sheet
3. Author normal declarations
   1. Specified in style sheet (can defer this until later)
   2. Specified in style element
   3. Specified in style attribute
4. Author important declarations
   1. Specified in style sheet
5. User important declarations
   1. Specified in style sheet

Sort Key (most significant first)
{0}     9 if user supplied style sheet, high
{0}     8 if author supplied style sheet, high
{0}     7 if style attribute, high
{0}     6 if style attribute, normal
{0}     5 if author suplied style sheet, normal
{0}     4 if user supplied style sheet, normal
{0}     3 if user-agent default style sheet, high
{0}     2 if user-agent default style sheet, normal
{0}     1 if inherited
{1}     count of number of ID attributes in selector
{2}     count of number of attributes and pseudo classes in selector
{3}     count of number of element names and pseudo elements in selector
{4}     sequence number in order added to list

1. Process user-agent default style sheet
2. Process user-supplied style sheet
3. process author-supplied style sheet
4. process STYLE element
5. process style attribute on all elements
6. expand all shorthand properties - the new properties have the same sort key as shorthand prop
7. Add initial values for all properties that don't have values

The various types of properties:
- Set by the style sheet explicitely
- Set at root level of hierarchy so that other elements can inherit (if no other ancestor)
- Set as initial value for certain elements - all properties have an initial value.  Some properties apply to only certain elements.
- Some properties inherit automatically, such as font-family.
- Some properties are set to inherit in the stylesheet.
- border-top-color etc. are set to the color property, which then inherits.

Properties either inherit, or are set to an initial value.  Those properties that inherit are set to initial value only at the top of
the tree.  Those props that are set to an initial value throughout the tree do not inherit.  It is either one or the other.

Following is my new theory of the correct algorithm:
- set all properties from the cascade.
- Set initial values for properties at the top of the tree.  These specifically need to be set for other properties that will
  inherit from them.
- create a matrix of all elements, and which properties need to be set for each element.
- iterate through the tree.

  SetAllValues
    for each element
      for each property
        call GetComputedPropertyValue  // implemented in a recursive fashion to set & get its computed value.

  GetComputedPropertyValue
    if (property is already computed)
      return the computed value
    if (property is set)
      compute value
      set the computed value
      return the computed value
    if (property is inherited (either because it was set to inherit, or because it is an inherited property))
      if (parent exists)
        call GetComputedValue on parent
        set the computed value
        return the computed value
      else
        call GetInitialValue for property
        compute value
        set the computed value
        return the computed value
    else
      call GetInitialValue for property
      compute value
      set the computed value
      return the computed value
  
  ComputeValue
    this needs to be specifically coded for each property
    if value is relative (em, ex, percentage, 
      if property is not on font-size
        GetComputedValue for font-size
        compute value accordingly
        return value
      if property is on font-size
        call GetComputedValue for font-size of parent
        compute value accordingly
        return value
      if value is percentage
        if margin-top, margin-bottom, margin-right, margin-left, padding-top, padding-bottom, padding-right, padding-left
          call GetComputedValue for width of containing block
    if value is absolute (in, cm, mm, pt, pc, px)
      return value
