Position (8 bytes): A byte array of a TSHR_RECT16 structure that specifies the left, upper, right, and lower edges of the region, in order.

realWidth (2 bytes): The width of the included bitmap, which MAY exceed the width that is specified in the position field because of padding in pixels.

realHeight (2 bytes): The height of the included bitmap, which MAY exceed the height that is specified in the position field because of padding in pixels.

Format (2 bytes): The bits per pixel of the bitmap.

compressed (2 bytes): MUST be set to 0x0000 or 0x0001. If set to 0x0001, the bitmap is compressed. If set to 0x0000, the bitmap is not compressed.

dataSize (2 bytes): The length, in bytes, of the data.

data (variable): Either the uncompressed bitmap data or a Compressed Bitmap structure.
