Pull request #4: RED-6019: Remove hidden text when processing OCR
Merge in RED/ocr-service from RED-6019 to master * commit 'a96260f77fd5b546a5d27d84f34861742f13ddff': RED-6019: Remove hidden text when processing OCR *moved InvisibleElementRemovalDto to private inner record of InvisibleElementRemovalService *added comments for color choices RED-6019: Remove hidden text when processing OCR *moved to release version of platform-dependencies *restored annotationProcessors RED-6019: Remove hidden text when processing OCR *code refactor *upgrade to java 17 RED-6019: Remove hidden text when processing OCR handled cases: Text which is transparent or is set to not render Elements outside of clipping path Elements that have been painted over by visible and filled Paths unhandled cases: Elements covered by widely stroked path Elements same color as background Any Text set to clipping with its many interactions with other elements
