PARAMETERS
v Specifies a pointer to an array of one, two, three, or four
elements, which in turn specify the s, t, r, and q texture
coordinates.
DESCRIPTION
fglTexCoord specifies texture coordinates in one, two, three, or four
dimensions. fglTexCoord1 sets the current texture coordinates to (s, 0,
0, 1); a call to fglTexCoord2 sets them to (s, t, 0, 1). Similarly,
fglTexCoord3 specifies the texture coordinates as (s, t, r, 1), and
fglTexCoord4 defines all four components explicitly as (s, t, r, q).
The current texture coordinates are part of the data that is associated
with each vertex and with the current raster position. Initially, the
values for s, t, r, and q are (0, 0, 0, 1).
NOTES
The current texture coordinates can be updated at any time. In
particular, fglTexCoord can be called between a call to fglBegin and the
corresponding call to fglEnd.

On Octane2 VPro systems, use of the texture q coordinate to achieve
projective texture effects will be processed on a per-vertex basis
instead of a per-pixel basis, unless the texture matrix is set up to be
projective. (A projective texture matrix, specified as 16-element array
M, is defined to be one in which any of the M[3], M[7], or M[11] array
elements is non-zero.) In addition, if either two-sided lighting or
fragment lighting or separate specular lighting is in effect, projective
texture effects will always be processed on a per-vertex basis.
