By default any pixel with alpha value greater than zero will be discarded. This is because transparent colors are not perceived
as is. For example fully transparent black would be seen white on a white background. So if you want to take transparency into account
when building a palette you have to specify this background color. You can do this with the second argument of Palette constructors.
Its default value is null, meaning a color won't be added to the palette if its alpha component exists and is greater than zero.
You can set it as an integer representing the color, then transparent colors will be blended before addition to the palette.
// we set a white background so fully transparent colors will be added as white in the palette
// pure red #FF0000 at 50% opacity will be stored as #FF8080 as it would be perceived
$palette = Palette::fromFilename('./some/image.png', Color::fromHexToInt('#FFFFFF'));
