98// oki, here are the psx gpu coord rules: poly coords are
99// 11 bit signed values (-1024...1023). If the x or y distance
100// exceeds 1024, the polygon will not be drawn.
101// Since quads are treated as two triangles by the real gpu,
102// this 'discard rule' applies to each of the quad's triangle
103// (so one triangle can be drawn, the other one discarded).
104// Also, y drawing is wrapped at 512 one time,
105// then it will get negative (and therefore not drawn). The
106// 'CheckCoord' funcs are a simple (not comlete!) approach to
107// do things right, I will add a better detection soon... the
108// current approach will be easier to do in hw/accel plugins, imho
