You must now include vips7 support explicitly with #include <vips/vips7compat.h> in your code just after including `vips.h`. The old vips7 names, such as `Rect`, were starting to cause problems with other packages like opencv.

float &VDisplay::YCW()

annoying to do this on such a useless class (I'm certain no one used these
