#4620 reused
legend.drawto displayunifiedhovers which is great improvement.But with an unresolved #4620 (comment) it is now difficult to understand what exactly is going on with the optional argument (
opts) passing todrawfunction and downstream.Also
optsis in fact essential (not optional) to most functions inlegend.drawwhile different sizes are computed and stashed into this object (with the intent IN & OUT).This PR is an attempt to address these internal issues before more progress on legends and unified hovers.
