/* TODO : old screen effect (called also sometimes scanline) */
Scanline is also used just at begin of '''Pinball_Dreams__PREVIEW.DSK''' (eagle draw)
=== TODO DONE : old screen effect (called also sometimes scanlinesometime Scanlines) ===
Scanline is also a simple visual effect to enable/disable, making games looking like old CRT monitors.
Problem : in CoreAmstrad, output VGA resolution is already at top (1 pixel is 1 pixel), CRT 768x288 is rendered into a 800x600 VGA, so I can't add an filter (without destroying VGA signal). CoreAmstrad is not using a simple 384x288 scandoubler like other core in VGA.
Another sort of scanline does exist, one line out of two is black, or darker. This It's this one shall be makableI implemented here : second lines are just 1/2 darker.
=== DONE : Monochrome option ===
