I am mapping texture to GL_POINT. My point size varies but lets say it's 5x5 pixels. Currently the whole point just samples single pixel from texture and point's texels are all that same color.

How can I (or can I) map it so that it all texels in point are sampled (1:1) from texture? i.e. if texture is 100 x 100px and point is 25x25px (not smoothed) the point should represent 1/4 region of texture and with 4 points I could represent whole texture.

Thanks.

-Mike
