1.0.0

New:
- Lowercase package name for CommonJS and AMD.
- `Underscore` dependency removal.
- Async rendering of facet cells (see example: https://api.taucharts.com/advanced/performance.html)
- Async spec calculation. Progress bar and warning for heavy charts.
- Optimize nearest element search.
- Highlight element and show tooltip when cursor is close to it.
- Stick tooltip and show action buttons on click, dim other elements.
- Raise highlighted element and group over others.
- Optimized repaints when sorting DOM nodes.
- Sparkline mode (hide ticks and grid lines (except zero) in small charts and facets).
- Improved chart labeling algorithm (hide label when it intersects points).
- Allow to show line and area points (`guide.showAnchors = 'always'`).
- UTC time scale, period scale and format (use `settings.utcTime = true`).
- Improved color legend (focus on click, toggle on icon click or CTRL+click; reset button).
- Horizontal size and gradient legend layout.
- Line and area transition during filtering.
- Improved variable size line appearance (circles connected with tangents like a brush).
- Show integer ticks for integer values.
- Smooth line, that doesn't exceed data points (`guide.interpolate = 'smooth-keep-extremum'`).
- Smooth interpolation for math data (`guide.interpolate = 'smooth'`).
- Hide equal labels at line.
- Improved key search performance for cached data.
- Detect Floating Axes background color.
- Configurable Export background.
- Reserve space for bar labels.
- Display existing values in Size Legend.
- Optionally apply Filter on mouse up (default) or immediately.
- Minimal radius for highlighted line points.
- Highlight zero tick when there are positive and negative values.
- Improved default number format.
- Highlight overlapped points by moving cursor around.
- Raise smaller bars over bigger for linear scale.
- Split size legend ticks by square root, reduced ticks count.
- Show X-cursor line for highlighted line point.
- Hide axis ticks for large density.
- Removed unnecessary polyfills (Map, WeakMap), added polyfills for IE (Array.from etc).
- Disable animation when too much elements.
- Smooth area (`guide.interpolate = 'smooth-keep-extremum|smooth|linear|step'`).

Fixed:
- Avoid base axis overflow.
- HTML characters in tooltip values.
- Cut labels when insufficient space on bar charts.
- Legend plugin breaks color brewer (#251)
- Layer plugin affected size scale.
- Scatterplot and line with size overflow chart.
- Bars overlap each other.
- Disabled scales rounding.
- Fixed displaying labels behind bars.
- Extending scale domain too much.
- Side ticks labels overflow.
- Linear scale domain with equal values.
- Axis labels are not rotated.
- Y-axis width calculation.
- Bars become black during filtering.
- Horizontal bars labels overlap.
- Hide tooltip on resize.
- Tooltip and legend highlight conflict.
- Custom color legend groups stay colored when disabled.
- Wrong colored bar position at order scale.
- Hide trendline labels.
