Adding new pixel codes at the end of the enumeration will soon create a
mess, so sort the pixel codes by type and then sort them alphabetically.
As the codes are part of the kernel ABI their value can't change when a
new code is inserted in the enumeration, so they are given an explicit
numerical value. When inserting a new pixel code developers must use and
update the next free value.
