Disable pango glyph position rounding

Browse source 
Chase 8c5b23e592

Pango rounds glyph position and widths to nearest integer, which leads to
font dimensions jumping around when rendering with a scale, causing text
geometry to jump around when changing scale.

Disable this rounding to make the geometry stable.
