Also, we should optimise the pngs. optipng tells us that at least this one isn't:

mitch@mitch-ubuntu:~/dev/qt-dev2/qtdoc$ optipng -o 7 -strip all examples/demos/qtoycustomizer/images/AngelWings_BaseColor.png
** Processing: examples/demos/qtoycustomizer/images/AngelWings_BaseColor.png
334x334 pixels, 4x8 bits/pixel, RGB+alpha
Reducing image to 3x8 bits/pixel, RGB
Input IDAT size = 51645 bytes
Input file size = 51714 bytes

Trying:
  zc = 9  zm = 9  zs = 0  f = 2        IDAT size = 44696
  zc = 9  zm = 8  zs = 0  f = 2        IDAT size = 44670
  zc = 9  zm = 9  zs = 1  f = 2        IDAT size = 44589
  zc = 9  zm = 8  zs = 1  f = 2        IDAT size = 44491

Selecting parameters:
  zc = 9  zm = 8  zs = 1  f = 2        IDAT size = 44491

Output IDAT size = 44491 bytes (7154 bytes decrease)
Output file size = 44548 bytes (7166 bytes = 13.86% decrease)

Also: ✅⬜⌛

⬜ Rename caret.svg -> cart.svg in images/icons/ 

⬜Remove duplicate images:

• qtCoins has svg and png version
• teddyBear has svg and 2 png versions
• Qtlogo has svg and png version
• builtWithQt has svg and png version
