Add page, index, and box to struct content_html_data. Implement html_replace_object() and html_find_target(). No longer combine box trees of frames and frameset (was causing crashes).
svn path=/import/netsurf/; revision=1874
More work towards frame targets: add target parameter to box_create(), and copy target down the box tree during construction.
svn path=/import/netsurf/; revision=1853
Work towards implementing link target frames: add target attribute to struct box, add frame to struct content_html_object and html_fetch_object().

Use given width as initial min/max width of fixed-width table columns. This improves the layout of certain tables with colspans.
svn path=/import/netsurf/; revision=1841
Fix certain cases of relative positioning, and make the recursion more efficient (don't recurse for BOX_TEXT).
svn path=/import/netsurf/; revision=1831
Fix layout min max bug with blocks with negative margins. Add assert()s to check that 0 <= min_width <= max_width at the end of each layout_minmax_X() function.
svn path=/import/netsurf/; revision=1813
Improvements to layout_minmax_line(). Fix width of floats / inline blocks without an explicit width (space for margins, borders, padding was added twice).
svn path=/import/netsurf/; revision=1781
Rewrite calculation of box minimum and maximum widths to improve layout of many pages. Move calculation of column types and border collapsing to box tree normalising stage, since they are layout independent. Add window height parameter to layout and make <html> and <body> at least window height.

Improve clarity of use of utf8_to_enc.
Remove use of curl_escape - url_escape does similar things, just better.
svn path=/import/netsurf/; revision=1766
Move acceptable character set determination to form submission time, rather thanat box tree creation time.
Use UTF-8 encoding, if specified, else use first specified encoding.
Improve use of utf8_to_enc - falling back to document encoding then 8859-1 where appropriate.

Allow images to be unloaded to disk or compressed in memory. Provide thumbnails in all tree windows (hotlist, history). Optimise the application initialisation times. Part 1 of 2.
svn path=/import/netsurf/; revision=1761
Lose cnv_str_local_enc and friends.
UTF-8 conversion functions now return an enumerated type allowing for fallbacks, if appropriate.
svn path=/import/netsurf/; revision=1744
More work on borders / padding / margins on inline elements. Add BOX_INLINE_END to hold the right border / padding / margin (left is in the BOX_INLINE).
svn path=/import/netsurf/; revision=1742
Fix text-decoration and borders on inline elements by replacing inline_parent in box structure with end_inline_children.
