This pull request removes code that causes quite a bit of overhead in the vector tile renderer: rendering a tile immediately after loading bypasses our logic that makes sure we only render tiles that are actually being used (
frameState.usedTiles
). That code originally was meant for better making use of a render frame, but in practice, it causes more work because it renders tiles during/after zoom animations that are not needed for rendering the target resolution.This pull request is best reviewed without looking at whitespace changes.
