Revision history for Perl extension Chart::Clicker.

2.26
  - Use min/max functions from List::Util rather than rolling my own
  - Refactor Series internals to more easily facilitate subclasses
  - Add HighLow series
  - Add CandleStick renderer

2.25
  - Add some new examples: Multiple-Axes, Multiple-Renderers and Shared-Axes
  - Add Context->share_axes_with method for convenience
  - Add font attribute to OverAxis decoration

2.24
  - Add label_font and tick_font attributes to Axis for changing each
    individually.

2.23
  - Don't uselessly add a Fill op to a Line renderer w/no shape
  - Properly handle the shape_brush attribute in the Line renderer
  - Remove default background_color from Plot

2.22
  - Line renderer will now stack if additive attribute is true.

2.21
  - More clever color allocator that attempts to space out colors at even hue
    spacings for predictable color schemes that are more pleasing and contrast
    enough to be easily differentiated.    
  - Bump Graphics::Color dep for color allocator test

2.20
  - Remove ghostly " - 5" that was fucking up additive ranges
  - Clamp Area "fade" gradients to the top of their areas, not the top of the
    plot
  - Add tick_label_color to Axis
  - Add label_color to Axis
  - Use real gray rather than translucent gray for grid to get rid of
    composited "joint" spots at line intersections
  - Add StackedArea renderer
  - Fix some errors in examples
  

2.19
  - Move some subs around in Clicker.pm, to no effect.
  - Take out some C-style loops because they apparently offend a loud majority
    of #moose (groditi and phaylon)
  - Hide border of "hidden" Axis
  - Set the type of Series keys & values to ArrayRef[Num] from ArrayRef
  - Fix 01-data-series.t which had an error in it.  Yay type checking!
  - Remove some useless, commented out code

2.18
  - Fix Line's shape attribute, which didn't do a damn thing
  - Draw Line's shapes in a separate loop so that the path works right
  - Remove Chart::Clicker::Shape
  - Add OverAxis Decoration
  - Add Clicker->over_decorations for adding decorations "over" the renderers
  - POD overhaul
  - Remove some long-commented-out code.

2.17
  - POD fixes
  - Split Grid's brush into two separate attributes: range_brush and
    domain_brush
  - Set an Axis' padding to 5 at the time it is created, zero it out in prepare
    if hidden.  This lets us remove some crufty code from Clicker.pm
  - Set a default color on the Axis' brush
  - Document Axis' tick_label_angle
  - Separate Grid's line drawing into two operations so that each brush
    can affect the output
  - Remove color from Grid, use each brush to set range/domain color
    separately
  - Remove some useless code from Plot
  - Add grid_over flag to Clicker.pm to allow grid over/under control
  - Rejigger Axis code so that each Axis' brush size affects it's
    border
  - Adjust paddings a bit.

2.16
  - Add Axis->tick_label_angle for rotating tick label
  - Add requirement for Math::Trig
  - Bump some deps

2.15
  - Fix META.yml
  - Add some POD to describe why NOT having a default context makes Clicker
    shit on itself.
  - Fix linear gradient in Area renderer.

2.14
  - Add examples directory
  - Don't add padding if axes are hidden.
  - Fix gradients in Area renderer

2.13
  - Remove some old code (was already commented out)
