MadButterfly: include/mb_graph_engine

annotate include/mb_graph_engine_cairo.h @ 936:a9abcdac0ae5

Fix issue of moving lightbar of testsvg.js. The lightbar does not move as expectation. It caused by compute trasnforming matrix that transform saved points from the space when saving points to current space. The transform matrix should not include matric of the owner of saved points.
