   Repeating a portion of a texture
  Hey I know that to repeat a texture in OpenGL you can do something like thisglTexCoord2f(0, 0);.....glTexCoord2f(4, 4);and that will repeat the whole texture 4 times vertically and horizontally but I want to repeat a portion of the texture a certain number of times vertically and horizontally for example i want to display the portion of the texture thats(.25, .25) to (.5, .5) 4 times across and 3 times down, How can I do this?   
  Can't do it in openGL.Go into Photoshop and cut/paste that portion you want into a new texture map.   ;  @TempHolderCheck sub-textures in OpenGL out. Sorry can't help more at the moment.   ;  oh this suxs
