12 * Calculate drawing bounding box like VSFilter
13 * Performance improvements
14 * Cache vector clip masks
15 * Avoid unnecessary glyph copies
16 * Various rendering fixes
19 * Parse numbers in a locale-independent way

35 * Embold glyphs if no bold variant is available, but was requested
36 * Modify \fax to be similar to VSFilter
37 * Trim spaces after line wrapping
38 * Fix border/shadow overlap combining in some cases

40 "Kerning: yes" in [Script Info] to enable it
41 * Slight bitmap handling optimizations
46 * Fixed cache lookup and overload problems
47 * All globals have been eliminated, libass is reentrant
48 * Dynamically allocate glyph and line buffers
49 * Fix up stroking of big borders
50 * Support empty lines (\N\N)
51 * Support for the following override tags:
52 \fax, \fay, \xshad, \yshad, \ybord, \xbord, \iclip, \u, \s, \p, \pbo
53 * Full subpixel accuracy for positioning
54 * PAR and rotation correction for EOSD rendering
55 * Drawing mode (including vector \clip and \iclip)

63 * Various fixes and updates to match VSFilter renderer.
64 * Support \blur tag and ScaledBordersAndShadow property.
65 * Fractional arguments and subpixel accuracy.
66 * Keep positions when pan-and-scan is used.
67 * Lots of bugfixes and other changes.
70 * Support '=' and '.' in style name in arguments to ass_set_style_overrides().
71 * Allow overriding [Script Info] parameters with ass_set_style_overrides().
72 * Add workarounds for some buggy fonts.
73 * Remove buggy workarounds for some other fonts.
74 * Fixed ass_set_line_spacing() (was broken before).
75 * Negative margin sizes are now used for image cropping.
76 * Better handling of behind-the-camera objects.
77 * Case insensitive parsing of SSA/ASS section headers.
78 * Improved font matching.
79 * When 2 styles have the same name, the later one is used.
80 * Fixed several other bugs.
