liberation-sans-1-2.png

Comparison of Liberation Sans 1 and 2 with ftview.

Left: Liberation Sans 1.07
Right: Liberation Sans 2.00
Byte code hinting used, *no* forced autohinting, grayscale anti-aliasing.

One can see that Liberation Sans 1 is very sharply rendered up to 17 point.
The vertical and horizontal lines are exactly one pixel wide and black,
there is not gray around them. From 18 point on, the vertical lines jump
to a width of 2 pixels.

For Liberation Sans 2, there is always some gray around the stems which 
makes it much more fuzzy and at sizes <= 17 point it makes it also look
much bolder.

A sharp byte code rendering as for Liberation Sans 1 of course causes
sudden jumps in boldness when increasing the font size because the 
vertical lines have a thickness of integer pixels, at some point it
jumps from a width of 1 pixel to a width of 2 pixels.

Without such bytecode, no such sudden jump in boldness appears when
increasing the font size.
