.SH DESCRIPTION
Enables texture perspective correction;
the RDP corrects the texture coordinate at each pixel.

Because of assumptions made by the RSP, perspective correction is \f3 required \fP
for all textured triangles (including those drawn with an orthographic projection).
.PP
When drawing texture rectangles (sprites), you should always 
disable perspective correction.
