AP_STREAM_RENDERING

Display rendered PDF appearance for annotation (i.e. its AP stream) in overlay.

Note that some annotation types (sound) are always displayed in overlay.

Annotations rendered using the AP stream are rendered as specified in the PDF document and are therefore displayed the exact same way on all PDF spec compliant PDF readers. Since documents can store arbitrary appearances for annotations, this means that PSPDFKit has to switch to non-AP stream rendering upon editing an annotation. This can lead to slightly slower annotation selection speeds than using PLATFORM_RENDERING in trade-off for higher rendering accuracy.
