|
|
|
|
*
|
|
|
|
* Cascading these properties correctly is hard because we need to
|
|
|
|
* cascade two properties as one, but which two properties depends on a
|
|
|
|
* third property ('direction'). We solve this by treating each of

* these properties (say, 'margin-start') as a shorthand that sets a
|
|
|
|
* property containing the value of the property specified
|
|
|
|
* ('margin-start-value') and sets a pair of properties
|
|
|
|
* ('margin-left-ltr-source' and 'margin-right-rtl-source') saying which
|
|
|
|
* of the properties we use. Thus, when we want to compute the value of
|
|
|
|
* 'margin-left' when 'direction' is 'ltr', we look at the value of
|
|
|
|
* 'margin-left-ltr-source', which tells us whether to use the highest
|
|
|
|
* 'margin-left' in the cascade or the highest 'margin-start'.
|
|
|
|
*
|
|
|
|
* Finally, since we can compute the normal (*-left and *-right)
|
2007-07-04 18:51:16 +00:00
|
|
|
* properties in a loop, this function works by modifying the data we

* will use in that loop (which the caller must copy from the const
|
|
|
|
* input).

COMPUTE_END_RESET(SVGReset, svgReset)
|
Landing of SVG_20020806_BRANCH, Bug 182533. Refactoring of SVG backend, new GDI+ and Libart rendering
backends, text support on Windows (GDI+), rudimentary text support on Linux (libart/freetype2), presentation
attributes, lots of bug fixes (see bug 182533 for dependency list).
