To delimit which symbols were considered experimental we used to use some preprocessor defines to gives experimental symbols an _EXP suffix so that anyone monitoring the ABI for changes would easily be able to discount changes made to clearly experimental functions. These days we simply rely on the gtk-doc "Stability: unstable" annotation to serve this purpose because changing the actual symbol name made it slightly more awkward to debug Cogl using GDB and was an extra mechanical step we decided we could do without. This patch removes the last remaining _EXP suffix defines in Cogl (cherry picked from commit 5a1c4a979e00accd492097cfb8f6a8d0fd8331bc)
