* Multiplied rain speed by 3, per Oni's request. * Disable weather density - force to 1 if weather draw distance, otherwise zero * Move the ceilingpic check into a more convenient part of the weather spawning loop. * `drawdist_precip_cons_t` - replaces "Infinite" with "None". * Disable the lowest normal draw distance (256), given... both kart and srb2 are basically unplayable like that. * Disable cv_drawdist_nights entirely.
