* add dimension selector sliders to czi view * version doc & version bump * cosmetic * fix build? * multi-dimension selection enabled in czi view * remove the parameterized reset function of the renderer it is not and is conceptually questionable doc updates & some minor improvements auto-update CZI-view when sliders are moved set initial window size fix windows build and msvc build For reasons I don not comprehend, on Windows, we must include =opencv2/core/mat.hpp= as the very last header in the =CvMatRender.hpp=. If this is at any other position building on Windows, compilation will break w/ all kinds of cryptic errors regarding OpenCV. When building w/ msvc =__PRETTY_FUNCTION__= is not defined. =ILog.hpp= now defines it. This should be revised to only be set when the compiler is msvc. For the time being, it is considered sufficient though.
