Unable to turn off doublescan and force 320x200 core output resolution for Tandy graphics, EGA or CGA #52

Description

@biffrapper

Perhaps I don't know how and someone could kindly point me in the right direction, but I tried all the traditional methods available in DOSBox.conf, and they do not work. When I check the output from the core within Retroarch it always remains at 640x400.

See, the issue I am having is I am properly trying to emulate the Tandy CM-5 RGB color monitor through shaders, which has a much higher dot pitch(really poor, actually), so gaps between the pixels are essential to truly capture the grainy features of the tube, which enhance how games of the era looked.

It would be nice if we had a feature that would allow us to disable doublescan or even force the output resolution we are trying to achieve, so we can inject into the shader stack the lower resolution and go from there. Prompt text in particular does not look right when doublescanned to a higher resolution.
