This fixes the loading of vkbd images from kbd subfolder:

This tries to make our code a bit more compliant with our code formatting
conventions. For future use, this is the command I used:
git ls-files "*.cpp" "*.h" | xargs sed -i -e 's/[ \t]*$//'
Sometimes we can have an 8bit file for example that has a palette of 16 colors or less, so we need to go by the bit depth rather than inferring the bit depth from the palette size.
