Declaration

THPDFDisplayListObjectKind= (dlokPath, dlokText, dlokImage,
  dlokShading, dlokUnknown);

HPDFPageRenderer

Value	Purpose
`dlokPath`	Path-painting object, recorded when path construction operators have produced a non-empty painted path
`dlokText`	Text-showing object, recorded when text operations have painted visible glyphs
`dlokImage`	Image XObject drawn through a `Do` operator
`dlokShading`	Shading pattern painted across the page media box
`dlokUnknown`	Fallback kind for an object falling outside the four recorded classes

Read entries with THPDFPageDisplayList.GetObject and filter by Kind to isolate paths, text, images or shadings for hit testing
dlokShading entries carry the media box as bounds, whilst path and text bounds come from the operators that painted them
The OperatorName field of the companion record gives the generating operator, such as re, Tj or Do
