Renderers

Each renderer must implement the following interface:

Size() (float64, float64)
RenderPath(path *Path, style Style, m Matrix)
RenderText(text *Text, m Matrix)
RenderImage(img image.Image, m Matrix)

Currently the following renderers are implemented:

Status

Native Feature	Raster	SVG	PDF	EPS	WASM	OpenGL	Gio
Fill path	yes	yes	yes	yes	yes		yes
Stroke path	yes	yes	yes	no	yes
Dashed path	yes	yes	yes	no	yes
Paint gradient	yes	yes	~yes	no	no
Embed fonts		yes	yes	no	no
Draw text		yes	yes	no	no
Draw image	yes	yes	yes	no	yes	yes	yes
EvenOdd fill rule	no	yes	yes	no	no	no	no

EPS does not support transparency
PDF and EPS do not support line joins for last and first dash for closed dashed path
OpenGL is really just a rasterizer to an OpenGL texture
