Release 0.6 changes:
- added baseline field to glyph metrics in glyphmaps.
- fixed GL backend regression failing to flush previously buffered text drawing before switching glyphmaps, resulting in parts of the text being drawn with the wrong font.
- implemented missing function:
dtx_draw_buffering. - fixed flush_user (user callback drawing) crash when there's no current glyphmap.
- stop emitting 0-length draw calls to user draw callbacks.
- minor android (OpenGL ES) compatibility fixes.
- fixed compatibility with gcc 10 or later (
-fcommon). - fixed reversed condition in unused utility function
dtx_utf8_from_char_code, which was always broken. - other minor build fixes.
