Feature Proposal

There are a number of legacy callbacks in scales that should either be removed or replaced with plugin hooks.

Legacy callbacks:

• beforeUpdate
• beforeSetDimensions
• afterSetDimensions
• beforeTickToLabelConversion
• afterTickToLabelConversion
• beforeCalculateLabelRotation
• afterCalculateLabelRotation
• beforeFit
• afterFit
• afterUpdate

Possible Implementation

Replace direct call(this.options[plugin]) with Scale._callHooks() as we've already done for beforeDataLimits, afterDataLimits, beforeBuildTicks, afterBuildTicks
