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

HPDFPageRenderer

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