6.0.0
feat: first round color all changed
chore: fix several typos
feat: (1) Support `preserveAspect` `preserveAspectAlign` `preserveAspectVerticalAlign` for series.map/geo/series.graph in box layout (lay out by left/right/top/bottom/width/height). (2) Support `clip` on geo/series.map (3) Support `roamTigger: 'global' | 'selfRect'` to switch roam area to global on only self bounding rect. (4) Support cursor style change when hovering the roaming enabled area to hint users. (5) Fix that center and zoom option does not work in series.sankey, and no relevant test case. (the roam is introduced in impl in #20321, due v6). (6) Fix the percent base of `center` (such as `center: ['40%', '50%']`) for all View coord sys based components/series (geo/series.map/series.graph/series.tree/series.sankey). #16904 introcuded percentage string here, such as '33%'. But it was based on canvas width/height, which is not reasonable - the unit may incorrect, and it is unpredictable if the `View['_rect']` is not calculated based on the current canvas rect. Therefore the percentage value is changed to based on `View['_rect'].width/height` since v6. Under this definition, users can use '0%' to map the top-left of `View['_rect']` to the center of `View['_viewRect']`. (7) Enhance the behavior for roaming area overlapping - the upper one has higher precedence. (8) Fix some `scaleLimit` missing. (9) Some refactor and clarification of `RoamController` and `roamHelper`.
feat(thumbnail): (1) Refactor thumbnail to a component for further extension, and add test cases. (2) Fix RoamController cursor style.
refact: put all core modules in the core dir. only do export in lib/echarts
feat(roam): Change cursor style to indicate the draggable area. (effect geo/insideDataZoom/treemap/sankey/graph roam)
feat(matrix & calendar): (1). Support matrix col/row size option. (2). Support corner content options in matrix. (3) Support body content options. (4). Support matrix `mergeCells`. (5). Fix and refactor the matrix style options, conserning their inheritance and z-order and flexibility. (6). Support declaratively layout other components (including grid/polar/geo/graph coord sys, and dataZoom/visualMap/legend/... components) based on `matrix`/`calendar`. And and enhance the echarts API `convertToLayout`/`convertToPixel`, custom series API `api.coord`/`api.coord` to support this feature comprehansively. Considering the previous "pie layout on coord sys", introduce the `boxCooridnateSystem` and `createBoxLayoutReference` to all of the components and echarts for the overall coord sys infrastructure. (7). Add some test cases to matrix and calendar.
fix(type): optimize types for dts bundling
