ggicons 0.1.0.9000

Icons with curved outlines (e.g. circles) no longer show faceted, polygonal edges when rendered large. Curves are now kept as Bezier paths and only flattened to a polyline at draw time, at a resolution adapted to the icon's actual rendered size and the output device's resolution, instead of a fixed low-resolution approximation baked in when the icon was first parsed. grImport2 is no longer a dependency; SVG path data is now parsed directly (via xml2).

Initial CRAN submission.

Added geom_icon(), a geom that draws an icon per row from the icon aesthetic, styled with colour/fill, size, alpha and angle. The icon aesthetic takes an icon vector from the icons package directly (e.g. icons::fontawesome$solid$rocket).
Added draw_key_icon(), the default geom_icon() legend key glyph.
Added scale_icon_identity() and scale_icon_manual(), plus scale_type.icon() method so aes(icon = ...) picks a sensible scale.
Added annotation_icon(), for drawing one or more icons at fixed positions, recycled the way annotate() recycles its arguments.
Added element_icon(), a theme() element (parallel to element_text()) for axis.text/strip.text/legend.text that draws any label matching a name in a supplied icons lookup as an icon, falling back to ordinary text for everything else.
Added geom_pictogram() and stat_pictogram(), for isotype-style unit charts, waffle/percentage charts and rating widgets: a value is turned into a grid of repeated icons, some fraction of them filled in. The grid can be fixed-size (a waffle chart) or grow with value (an isotype chart), and reads as a bar/column chart when x or y is left unmapped.
Added guide_pictogram() and scale_value_continuous(), which together give geom_pictogram()'s value aesthetic a default legend spelling out the amount one icon represents (e.g. "= 1000").
