Doom 3 Can Do It Too code mods file

These are very valuable code mods that implement things like water (missing from Doom 3 but can be put back in via a shader), 3D skyboxes (were implemented in Doom 3's expansion Resurrection of Evil but are missing from vanilla), and bloom. They were produced for a now defunct mod called Doom 3 can do it better Euro. These files were found on the mod's website which is now only accessible in an archival form.

These code mods are credited to dante_uk, Lloyd, inolen and idiom, SantaClaws, Daniel Schimmer and iceheart.
