6.1.0
fix: (1) Fix geo roam (pan and zoom) causes visual artifacts -- geo coord sys and its content (e.g., scatter) should visually align during roaming animation and manual roam. (2) Refactor to uniform roaming impl (via RoamController and ViewCoordSys) and clarify `updateTransform` and related code. (3) Enable scatter and effectScatter clip in geo. (4) Fix aria: palette is modified to ec instance local rather than global, which is more reasonable. (5) Fix map series roaming bug: roam and then click legend hide the first series and then roam and then click legend to restore the first series, the map should not jump.
fix(progressive): (1) Fix that candlestick large data progressive rendering was broken by Doji feature. (2) Fix bar large and progressive might throw NPE. (3) Follow the fixing of progressive rendering in zrender#1151 (3) Fix parallels did not clear previous rendered content when switching between progressive and normal mode. (4) Fix that chart.on('finished') event might not be called in some edge case (when multiple iterations are executed in one frame at the end).
