 = Bug details =
 Sierra games such as King's Quest 6 that have the "Enable high-resolution
 graphics" option in ScummVM use nearest-neighbor scaling to upscale the
 backgrounds from the original 320x200 to 640x4?? when this option is
 selected, as per the original engine's Windows 3.1 implementation.

 Unfortunately this also has the nasty side-effect of reducing the
 effectiveness of ScummVM's scaler/filtering features.

 Given that ScummVM already lets you do many things not supported by the
 original games' engines, it would be nice if there were an option to
 perform at least a bilinear upscale of the backgrounds instead of only
 nearest-neighbor.

 GOG or CD-ROM releases, DOS or Windows 3.1 flavors

 N/A. This is an enhancement.
