* remove unfinished polygon and remove selectable for shapes in polygon mode * make group and polygon position remain inside canvas area * click through transparent area in grouped object * add some shortcuts for basic usages * tools button icon in center & switch mode border * fix load svg image * basic rtl support, panzoom have issues in rtl mode * better zoom option both in ltr and rtl * handle zoom event in mask editor * add h button to handle toggle mask * add more mime type * use capital M (shift+m) for toggle mask * allow io shortcuts in mask editor only * make other shapes also remain in canvas bound area * better zoom implementation, zoom from center add zoom to resize event listener * add a border to corner to handle blend of control * add refresh button to go to selection menu * add tooltip to shortcuts and also add shortcut for other tools * make opacity remain in same state when toggled on * opacity for group/ungroup objects * update shortcuts implementation
