/* Rough notes about the relationship of borders and backgrounds in CSS3;
|
||||
* see http://www.w3.org/TR/css3-background/ for more accurate details.
|
||||
*
|
||||
* - Things are drawn in 4 layers, from the bottom:
|
||||
* Background color
|
||||
* Background image
|
||||
* Border color or border image
|
||||
* Content
|
||||
* - The background color, gradient and image extend to and are clipped by
|
||||
* the edge of the border area, so will be rounded if the border is
|
||||
* rounded. (CSS3 background-clip property modifies this)
|
||||
* - The border image replaces what would normally be drawn by the border
|
||||
* - The border image is not clipped by a rounded border-radius
|
||||
* - The border radius rounds the background even if the border is
|
||||
* zero width or a border image is being used.
|
||||
*
|
||||
* Deviations from the above as implemented here:
|
||||
* - Nonuniform border widths combined with a non-zero border radius result
|
||||
* in the border radius being ignored
|
||||
* - The combination of border image and a non-zero border radius is
|
||||
* not supported; the background color will be drawn with square
|
||||
* corners.
|
||||
* - The combination of border image and a background gradient is not
|
||||
* supported; the background will be drawn as a solid color
|
||||
* - The background image is drawn above the border color or image,
|
||||
* not below it.
|
||||
* - We don't clip the background image to the (rounded) border area.
|
||||
*
|
||||
* The first three allow us to always draw with no more than a single
|
||||
* border_image and a single background image above it.
