Functions
std::optional< std::pair< size_t, size_t > >	OleEmbeddedCompoundFile (const std::vector< uint8_t > &aPayload)
	The 26-byte prologue stores length at offset 22 and length plus 22 at offset 0.

OLE_IMAGE_PAYLOAD	ExtractOleImage (const uint8_t *aCfb, size_t aSize)
	Prefer CONTENTS, then OlePres000, then the native stream.

OLE_IMAGE_PAYLOAD	ExtractOleImageFromPayload (const std::vector< uint8_t > &aPayload)
	Read the picture out of an OLE object payload that carries the 26-byte prologue.

bool	OleMakeBmpFromDib (const std::vector< uint8_t > &aDib, wxMemoryBuffer &aOut)

std::vector< uint8_t >	OleExtractEmbeddedEmf (const std::vector< uint8_t > &aWmf)
	Reassemble an EMF carried by WMF META_ESCAPE_ENHANCED_METAFILE records.

std::vector< uint8_t >	OleExtractCiImage (const std::vector< uint8_t > &aPayload)
	The CI marker follows the preview DIB; the raster has a counted decimal length.

VECTOR2I	OleWmfRenderSize (int aNaturalWidth, int aNaturalHeight, int aMaxWidth, int aMaxHeight, double aTargetAspect)

bool	OleRenderWmf (const std::vector< uint8_t > &aWmf, int aMaxWidth, int aMaxHeight, wxImage &aImage, double aTargetAspect)

bool	OleRenderMetafilePreview (const std::vector< uint8_t > &aWmf, int aMaxWidth, int aMaxHeight, wxImage &aImage, double aTargetAspect, bool *aUsedEmbeddedEmf)
	Render a metafile preview, preferring an EMF the WMF carries over the WMF itself.

wxString	OleDescribeImagePayload (const std::vector< uint8_t > &aPayload)
	Include leading bytes when the payload format is unknown.
