Demoscene related stuff for GNU/Linux.

tools/fngen.c: - Function table generator for import-by-hash code to use.

tools/ulink.c: - Minimal linker to generate small ELFs. - (with some intro-specific constants hardcoded into the program header...)

src/fn_table.txt: - List of functions to import by hash, input to fngen.

src/intro.s: - The actual intro code.

src/shader.frag: - Fragment shader used by the intro.

Run make and you should get a 728 byte ELF that looks like this:

TODO:

- music and stuff
- learn how to make snazzier shaders
- compress the shader code somehow?
- use the shell script self-extract trick?
