MOHAWK: MYST: Assertion failure due to recent cos/sin table changes

Reported by: lotharsm Owned by: dafioram
Priority: high Component: Engine: Mohawk
Version: Keywords:
Cc: dafioram Game: Myst


The recent cos/sin table changes introduced a regression that leads to an assertion failure in MYST when trying to start a new game. The assertion failure happens right after the start of the game, where the intro movie is supposed to be played.

    COMMON: allow cos/sin number of points to be more flexible

    Previously, the cos/sin table had to be a power of 2, but there
    are many use cases where the number of points is not necessarily
    a power of 2 so this change the constructor so it now takes
    in the number of points rather than the number of points as the
    exponent of a power of 2.

    The restriction is that the size must be divisible by 4.
