Brush mouse-move handler.

Widget-space coordinates are only used by the top-level dispatcher. Absolute output-image coordinates come from mask_gui->pos, normalized output-image coordinates come from mask_gui->rel_pos, and raw-space edits are derived locally through the appropriate backtransform helper.

get the border handle position corresponding to a node, by looking for the closest border point in the resampled points of the form GUI.

This is used when we have to initialize control points for a node that has been set manually by the user, so we want to get the corresponding handle position to eventually match a catmull-rom like spline. The values should be in orthonormal space.

Parameters

gui_points	the form GUI points
node_count	the number of nodes in the form
node_index	the index of the node for which we want to get the border handle position
x	the x coordinate of the border handle position (output)
y	the y coordinate of the border handle position (output)

Returns

gboolean TRUE if the border handle position has been successfully retrieved, FALSE otherwise
