/// \brief special trick routines to make some SW tricks look OK with
/// HW rendering. This includes:
/// - deepwatereffect (e.g. tnt/map02)
/// - invisible staircase (e.g. eternal/map02)
/// - floating ceilings (e.g. eternal/map03)
///
/// It is not guaranteed that it looks identical to the SW mode,
/// but it looks in most of the cases far better than having
/// holes in the architecture, HOM, etc.hw_trick.c is a file that attempts to recreate vanilla Doom mapping exploits, such as the deep water trick, and invisible staircases (see testholes.wad, enable gr_correcttricks.) Those effects are not relevant in the context of SRB2, and usually breaks some maps (sometimes with intended effects) when enabled. This branch removes hw_trick.c and the corresponding console variable.
