Previously, node selection made no distinction between a frame node and other nodes. So a frame node would be selected by their whole rect or center (depending on box/lasso/circle select). As a consequence of this, box and lasso could not pratically be started inside a frame node (with the intention to select a subset of contained child nodes) because the frame would be selected immediately and tweak-transforming started. Circle selecting would always contain the frame node as well (making transforming a subset of nodes without also transforming the whole frame impossible). Now change selection behavior so that for all selection modes only the border [the margin area that is automatically added around all nodes, see note below] of a frame node is considered in selection. This makes for a much more intuitive experience when arranging nodes inside frames. note: to make the area of interest for selection/moving more obvious, the cursor changes when hovering over (as is done for resizing). note: this also makes the resize margin consistent with other nodes. note: this also fixes right resize border (was exclusive instead of inclusive as every other border) Also fixes T46540.
