Fixed calculation of glyph dimensions on Windows

Fixed calculation of glyph dimensions on Windows
...
The dimensions in the `DWRITE_GLYPH_METRICS` are a bit special:
the `rightSideBearing` is measured from the right edge of the
character boundary, not the left edge.
So, doing (right - left) would usually return a negative or very
small number, which, when casted to a u32 in an unsafe block, would
silently overflow to a very large number and make webrender crash.
Therefore, in order to calculate the metrics correctly, we have
to first calculate the full width of the character, then subtract
the right and left edges, same width the height.

Add a new varying to the stencil AAA fragment shader for simplicity.
...
The new `vXDist` values *can* be deduced simply from the `vUV` values
and first-order derivatives thereof, and therefore they're technically
redundant. However, calculating them in this way increases the
complexity and ALU load in the fragment shader. It's simpler to just
compute the additional values in the vertex shader and use
interpolation.

Port Pathfinder to use Lyon for Bézier curve math.

This removes a whole lot of code from `pathfinder_path_utils`. Hopefully

These changes regress quality of stroke widths for cubic curves, because
they move fill-to-stroke conversion before cubic-to-quadratic
conversion. To fix that, we will need to recursively subdivide when
doing fill-to-stroke conversion.
