Werner Lemberg edcf817efa [docmaker] Replace `name' attribute of `<a>' with `id'.
* src/tools/docmaker/tohtml.py (HtmlFormatter::block_enter): Do it.
2014-11-27 19:28:48 +01:00
Werner Lemberg 26d699ed84 * src/tools/docmaker/tohtml.py: Remove remaining `width' attributes.
For `Index' and `TOC' links, we now simply use the `text-align' CSS
property of `<td>' to enforce flush-left and flush-right,
eliminating the hack with an empty, full-width `<td>' element
inbetween.

The change also enforces the same (smaller) size for all index and
TOC links.

Werner Lemberg dd3fee072c * src/tools/docmaker/tohtml.py: More HTML table refactoring.
Replace some `<table>' tags with `<div>' to simplify structure.

Move `bgcolor' attribute to CSS.

Replace most `width' attributes with CSS.  The remaining instances
(providing a similar effect as LaTeX's `\hfill' command) are removed
in a later patch.

Jarkko Pöyry 96341dc378 [cff, pfr, psaux, winfonts] Fix Savannah bug #43676.
Don't cast cmap init function pointers to an incompatible type.

Without this patch, the number of parameters between declaration and
the real signature differs.  Calling such a function results in
undefined behavior.

  ISO/IEC 9899:TC3 (Committee Draft September 7, 2007)
    6.5.2.2 Function calls
      9 If the function is defined with a type that is not
        compatible with the type (of the expression) pointed to by
        the expression that denotes the called function, the
        behavior is undefined.

On certain platforms (c -> js with emscripten) this causes
termination of execution or invalid calls because in the emscripten
implementation, function pointers of different types are stored in
different pointer arrays.  Incorrect pointer type here results in
indexing of an incorrect array.
