Patrick Walton 6c996981a3 Fix some transform issues and implement transformed radial gradients in SVG. 
In particular, this fixes the usvg-to-Pathfinder transform conversion and the
definition of `Transform2F::row_major()`.

Makes `drops.svg` from the MPVG samples work.

Patrick Walton e598249186 Use column vector length to extract scale from matrices. 
Closes #298.

Patrick Walton 895f73096e Switch back to instanced drawing for tiles. 
Improves tile build time by something around 2x in the NanoVG demo.

Patrick Walton 794dd55038 Add some implicit conversions between scalars and vectors where appropriate 2020-04-01 17:20:32 -07:00
Patrick Walton 93f5fbc6d2 Add convenience constructors: `vec2f`, `vec2i`, `Vector2F::zero()`, 
`Vector2I::zero()`

Patrick Walton 0b0c45a49a Collapse linear gradients down to a single 256x1 sliver instead of a 256x256 
square

Patrick Walton 5a21557a6d Implement basic linear gradients. 
This is not a very efficient implementation yet, but it seems to work.

Patrick Walton a66ed4c073 Specify tile texture coordinates as an affine transform. 
Part of the groundwork for gradients.

Patrick Walton bcac119324 Rename `Transform2DF` to `Transform2F` and `Transform3DF` to `Transform4F` 2019-07-11 14:59:10 -07:00
Patrick Walton b886c157c1 Use 2-lane instead of 4-lane SIMD types for 2D vectors. 
Also, this commit rewrites the `add_fill()` method to stop using shuffle
instructions, which can be slow and make the code overly complicated. The
shuffle instructions have been removed from the various SIMD backends.

Patrick Walton 431dcf3d2e Rename `pathfinder_geometry::basic` to simply `pathfinder_geometry`, and move 
the remaining code in that crate to a new crate, `pathfinder_content`

The old hierarchy was confusing.
