  ## Merging appearance overrides
  -A [Viewport]($frontend) can have any number of [FeatureOverrideProvider]($frontend)s, each of which can specify how to override the appearances of elements, models, and/or subcategories. Sometimes, multiple providers want to override aspects of the appearance of the same objects, which produces conflicts. The existing methods for defining overrides - [FeatureOverrides.overrideElement]($common), [FeatureOverrides.overrideModel]($common), and [FeatureOverrides.overrideSubCategory]($common) - each take a boolean `replaceExisting` argument that defaults to `true`. This means that if one provider overrides the line width of an element and another wants to override the same element's transparency, the caller's only choice is to either replace the existing override, resulting in only transparency being overridden; or keep the existing override, resulting in only transparency being overridden. But in most cases, the better result would be to **merge** the two sets of overrides such that both transparency and line width are overridden.

  A new [FeatureOverrides.override]($common) method has been introduced to support merging appearance overrides. The caller can specify one of four strategies for dealing with conflicts, or accept the default:
