Currently only by changing the source code, I fear.

In src/hid/common/hidgl.c insert this line before line 155:

  glPointSize(3.0);

The area then reads like this:

  ...
  glEnableClientState (GL_VERTEX_ARRAY);
  glVertexPointer (3, GL_FLOAT, 0, points);

  glPointSize(3);
  n = 0;
  for (x = x1; x <= x2; x += PCB->Grid)
    {
  ...

That's a hack, of course. If you want a more permanent solution, please open a bug report: https://bugs.launchpad.net/pcb The "right" version would be to define something like a pixel -> screen size scale (resolution), either by a user preference or by querying the operating system, then to define this size not by number of pixels, but by size on screen.
