PK_blend_trim_extent_t

typedef int PK_blend_trim_extent_t;

Used in:

PK_FACE_make_3_face_blend_o_t

This datatype is used to specify additional control of trimming operations.
It stipulates the extents of which walls should be considered when trimming
to determine the extent of the blend.
It has two values:

    PK_blend_trim_extent_all_c        Consider the extent of all three walls
                                      during trimming to determine the blend
                                      extent.
    PK_blend_trim_extent_sides_c      When trimming in three face blending
                                      ignore the extent of the central wall,
                                      and only use the left and right side
                                      walls to determine the blend extent.
