2261f81762
This change refactors the IRect and FRect types into a single templated type Rect<T>, which allows the implementation to be shared across both variants. This change also adds convenience getters for the rect widths and heights, and updates callsites accordingly. Change-Id: I38509631d57706266186a7b7fa21bd43c0860890
