/*
 * flags for G_SETGEOMETRYMODE
 * (this rendering state is maintained in RSP)
 *
 * DO NOT USE THE LOW 8 BITS OF GEOMETRYMODE:
 * The weird bit-ordering is for the micro-code: the lower byte
 * can be OR'd in with G_TRI_SHADE (11001100) to construct
 * the triangle command directly. Don't break it...
 *
 * DO NOT USE THE HIGH 8 BITS OF GEOMETRYMODE:
 * The high byte is OR'd with 0x703 to form the clip code mask.
 * If it is set to 0x04, this will cause near clipping to occur.
 * If it is zero, near clipping will not occur.
 *
 * Further explanation:
 * G_SHADE is necessary in order to see the color that you passed
 * down with the vertex. If G_SHADE isn't set, you need to set the DP
 * appropriately and use primcolor to see anything.
 *
 * G_SHADING_SMOOTH enabled means use all 3 colors of the triangle.
 * If it is not set, then do 'flat shading', where only one vertex color
 * is used (and all 3 vertices are set to that same color by the ucode)
 * See the man page for gSP1Triangle().
