Thanks Iain, that's perfect! I'd swear I had looked for them there a few weeks ago, but don't remember seeing them.
This still leaves me in a bind tho, because of the specific way I'm trying to use them... but I'm trying to use these inside of another macro definition, like so:
#define NEWSHADER bounds(0, 0, $SCREEN_WIDTH, $SCREEN_HEIGHT), colour(20, 20, 20,235), fontcolour(255, 255, 255, 255), visible(0)
That way any instrument that's imported the file can just add one like so:
image $NEWSHADER, identchannel("reset-tint")
Currently that doesn't appear to work... I know I've given Rory quite the headache already with regards to macros, so any alternate suggestions that would make it equally portable are welcome... I'm trying to avoid having to define bounds and colors for it every time it's used.
