Can anyone tell my small brain what I should do to correct the texture coordinates in the patch below so that the texture fills the whole plane that is created?

(My end goal is to create a patch so I can move the corners of my texture to make irregular, rhomboid shapes so in order to correct for projection distortions. Like an irregular keystone kind of thing.)

texcoords-on-jit-gl-mesh

texture coordinates cannot be less than 0 

so make a separate matrix for the texcoords

texture coordinates cannot be less than 0 
between 0.0 and 1.0

so make a separate matrix for the texcoords


attach this to your gl.mesh to adjust further (courtesy of wes smith)

on the gl.mesh, try:
tex_map 1 
tex_plane_s 0.5 0. 0. 0.5
tex_plane_s 0. 0.5 0. 0.5

I just added a pictslider in a subpatcher that lets me move the corner of the plane around so I can cornerpin it to a projection surface.

brilliant!  just the info I needed.

thank you both.  you rule!
