Array< TransDataEdgeSlideVert > transform_mesh_uv_edge_slide_data_create	(	const TransInfo *	t,

		int *	r_group_len )

We need at least 3 points to calculate the intersection of prev-curr and next-curr destinations.

| | | | | | prev -— curr -— next

Find the best direction to slide among the ones already computed.

Parameters

curr_prev	prev state of the #SlideTempDataUV where the faces are linked to the previous edge.
l_src	the source corner in the edge to slide.
l_dst	the current destination corner.
