Steps to add new icons:

• Install FontForge
• Load a freely licensed font and mpv's glyph directory, for example: fontforge Symbola.ttf TOOLS/mpv-osd-symbols.sfdir
• Check the Unicode hex value of the desired character (g-a in vim)
• Scroll until that value in the font window and click it
• Copy the selected glyph (Ctrl+c)
• Focus the window with TOOLS/mpv-osd-symbols.sfdir
• Click an unused character slot
• Paste the glyph (Ctrl+v)
• Save (Ctrl+s)
• Edit the numbers in the glyph file to match the size and position of adjacent icons (TODO: find a better way)
• Run sh TOOLS/gen-osd-font.sh
• Add the icon to osc.lua following the instructions there
