Replace d by plotattributes

Replace d by plotattributes

The goal is to replace d by plotattributes inside @recipes. See here for the original issue. Of course that is a change that breaks a lot of packages, so there was a plan how to coordinate things. I started implementing it, but @mkborregaard wanted to wait until julia version requirement is bumped to 0.7. However I probably won't have time for this when we upgrade to 0.7. So I propose here a better plan, where almost all work can be done now, without breaking anything.

Step 1

• Allow usage of both d and plotattributes inside @recipes. Without any deprecation warning.
• Tag a new release for RecipesBase.

I searched all packages that depend on Plots or RecipesBase and none of them used the word plotattributes inside a recipe. So this is a safe step.

Step 2

• Update d to plotattributes inside Plots.
• Tag a new release for Plots.

Doing this after tagging Step 1 is important so all tests can pass.
After this step it is safe to use plotattributes instead of d in any other package.

Step 3

PRs to all packages that depend on Plots or Recipes to replace d by plotattributes.
While a lot of packages depend on these, only a few are using d:

• DynamicMovementPrimitives
• ImplicitEquations
• LPVSpectral
• PlotRecipes
• StatPlots
• SymPy
• TimeSeries
• ValueHistories

Step 4

• When upgrading to julia 0.7 add depwarning for usage of d.

Step 5

• When upgrading to 1.0 remove d altogether.

Do the maintainers of Plots agree with this?

To me this sounds like a great plan!

Yes, sounds good.
