direction over multiple regions. This allows a single bridge to be drawn over holes, which are too close to each other to allow for separate bridges. Fixes Bridging-Angle not optimal https://github.com/prusa3d/Slic3r/issues/12 Re-allowed adaptive infill line width for solid infills. The adaptive infill line width works in some circumstances, see Issue #15, but the original implementation often changed the line width too aggressively. The current implementation limits the line width change to 20%. Fixes Gaps between infill and perimeter leads to errors in laydown on following layer https://github.com/prusa3d/Slic3r/issues/15
