Bug Fixes

◼Fixed: Potential thread safety issue when loading iPhone-style HEIC images via DLL
◼Fixed: TIEMetaListView does not reset some integer EXIF properties when clear value
◼Fixed: TWAIN multi-page acquire may not terminate when the source never reports pendingXfers.Count = 0 (e.g. some Kyocera ADF drivers)

Changes to Method Parameters

◼Added: TIEBitmap overload for TImageEnMView.PaintTo

Demo Changes

◼Added: Brush Step performance options in BrushTool demo (Demos\ImageEditing\BrushTool\PaintBrush.dpr)
◼Added: Various improvements to Complete Editor demo (Demos\ImageEditing\CompleteEditor\PhotoEn.dpr)
◼Added: Various improvements to IEVision demos (Demos\IEVision\*)

Compatibility Issues

◼Changed Behavior: Prior to v15.2.2, ThumbHeight = -1 would return a thumbnail that was 3/4 of the height of ThumbWidth. ThumbHeight = -1 now means the thumbnail height will match the height of the control
◼Changed Behavior: CAP_XFERCOUNT is only set when the application sets AcceptedImages
◼Changed Behavior: TImageEnView.BrushTool.BrushStep now defaults to 1 (instead of 0)
◼Changed Behavior: MsVfW32.dll and avifil32.dll are delay-loaded by default (IEDelayVFWDllLoading in ie.inc). They load on first AVI/VFW use instead of at process start. Undefine IEDelayVFWDllLoading to restore eager loading
◼Updated DLL: Exception on load if iewebp32/64.dll is too old (missing animation exports)
◼Updated DLL: For HEIF support use the combined HEIF loading DLL, ieheif32/64.dll, instead of libheif.dll, dav1d.dll, de265.dll, libx265.dll
