CSS style declaration bytecode
==============================
Format
------
<opcode+flags+value> [<parameters>]
<opcode+flags+value> is 32 bits wide:
bits 18-31: value
bits 10-17 : flags
bits 0-9 : opcode
The 8 bits of flag data are defined as follows:
bits 2-7: MBZ
bit 1 : value is inherit
bit 0 : value is important
The 14 bits of value are opcode-specific.
Parameters are opcode-specific. Each parameter must begin on a 4 byte boundary.
Datatype storage
----------------
All numeric values are stored in a 32bit wide field. This field contains
a fixed point value with 22 bits assigned to the integer part and 10 bits
assigned to the fractional part.
Strings are stored as a 32bit index into a table of interned string pointers.
The table is found in the stylesheet object.
CSS dimensions are stored as two 32bit values: <length, units>.
Length is a 32bit numeric value (as described above) and unit is as follows:
bit 8 clear => length unit
bits 9-31: MBZ
bits 0-7 :
00000000 => px
00000001 => ex
00000010 => em
00000011 => in
00000100 => cm
00000101 => mm
00000110 => pt
00000111 => pc
bit 8 set => percentage unit
bits 9-31: MBZ
bits 0-7 : MBZ
bit 9 set => angle unit
bits 10-31: MBZ
bit 8 : MBZ
bits 0-7 :
00000000 => deg
00000001 => grad
00000010 => rad
bit 10 set => time unit
bits 11-31: MBZ
bits 8-9 : MBZ
bits 0-7 :
00000000 => ms
00000001 => s
bit 11 set => frequency unit
bits 12-31: MBZ
bits 8-10 : MBZ
bits 0-7 :
00000000 => Hz
00000001 => kHz
CSS colours are stored as one 32bit value. See "Colour" for their format.
Shorthand properties
--------------------
The CSS shorthand properties are handled by decomposing them to their
component parts, and then creating bytecode for these.
For example, "background: red none no-repeat scroll left top !important;" would
be decomposed to:
background-color: red !important;
background-image: none !important;
background-repeat: no-repeat !important;
background-attachment: scroll !important;
background-position: left top !important;
and bytecode generated for each of these properties.
The full list of CSS 2.1 shorthand properties is:
background
border-color
border-style
border-{top,right,bottom,left}
border-width
border
cue
font
list-style
margin
outline
padding
pause

bits 3-6: MBZ.
bit 7 clear => keywords:
bits 0-6: 0000000 => auto,
other => rffe.
If the value is rect(top, right, bottom, left), then bits 3-6 encode
which of <top>, <right>, <bottom>, <left> is set to auto. The
subsequent parameter list is then 4 - <auto_side> entries long.
Each entry is a dimension. Entries are always ordered top, right,
bottom, left.
For example,
clip: rect(10px, auto, auto, 10px)
would produce the following bytecode:
<02c00017> <00002800> <00000000> <00002800> <00000000>
18 - color

0000011 => close-quote,
0000100 => no-open-quote,
0000101 => no-close-quote,
other => rffe.
If the value is not "normal", "none", or "inherit", then there is
a parameter list. Each item is preceded by a <value> word which
declares the type of the next item. The list is terminated by a
word with all bits set to zero (the encoding for "normal").
For example,
content: open-quote url('http://example.com/')
" : " attr(name) " " counter(x) "." counters(y, ".")
close-quote;"
would result in the following bytecode:
<00080019>
<00000081> <ptr to "http://example.com">
<00000080> <ptr to " : ">
<00000084> <ptr to "name">
