common/pango: Disable glyph position rounding
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. This is disturbing
when text buffers change scale, and also mean that the text geometry
calculations in sway_text_node are incorrect.
Disable this rounding to make the geometry stable.
