Node Editor: Draw link lines to output nodes dashed
Draws bezier links to output nodes dashed to separate them from usual node connections.
Note: Changed GL_LINES to GL_LINE_STRIP here as drawing is pretty ugly otherwise, but there is this comment above:
/* XXX using GL_LINES for shaded node lines is a workaround * for Intel hardware, this breaks with GL_LINE_STRIP and * changing color in begin/end blocks. */
Maybe there are better solutions to keep supporting the Intel cards than using GL_LINES instead of GL_LINE_STRIP? Would really prefer to keep the GL_LINE_STRIP as it has a noticeable influence on the dashed drawing (@Antony Riakiotakis (psy-fi), maybe you know a good workaround? Or maybe this has even been solved on Intel side?)
