Why this instead of unsigned char pRGB[4]? I wouldn't use malloc, especially if that's "per-pick"

glVertex3f( +0.5f, -0.5f, +0.5f);
glVertex3f( +0.5f, +0.5f, +0.5f);
glVertex3f( -0.5f, +0.5f, +0.5f);
glEnd();
I'd highly recommend using
vertex arrays instead of slow, deprecated and often impractical immediate mode. Also, if some day tinygl is improved to support VBO, then you can get some serious speedup from modifying the vertex array code to use VBO instead (it's basically only a few additional function calls around what you have in vertex arrays.)
