What's new in 1.7.1

1.7.1 fixes the latest reported crashes, rendering problems, installer registration, file navigation, and editing issues, while adding perspective correction and app-link support. Added - Transform can now correct trapezoidal perspective distortion in pages photographed at an angle. Turn on perspective correction, drag four corner handles onto the photographed page outline, and Apply converts that quadrilateral into a straight rectangular page at the full transform resolution.
