Summary: Draw grid with a different color when view is zoomed out

Initial Comment:
This patch defines a new color "grid-blend-color" which is a darker or lighter variant of the "grid-color" (depending on the color used for background). This color is used for drawing the grid when grid is in fixed mode and distance between grid points falls bellow the number of screen pixels specified in "w_current->grid_fixed_blend_threshold".

The end result is that the schematic is a bit more readable when zoomed out and grid points are still well visible when zoomed in. This is basically a primitive simulation of rendering grid points that are less than one pixel in diameter.
