Added support for HEVC video. Refer to the Readme.txt file for limitations
on HEVC support.
Changed the ‘Display HD Full-Sized’ option to a ‘Zoom’ option. The new
option allows for scaling the video at full-size, half-size, or quarter size.
Removed the use_D3D parameter from DGSource(). It is now read automatically
from the DGI file.
