#17355: SCI: GK1: High resolution graphics mode scales text and low-res graphics
unevenly (200→480 vertical stretch)

Reporter:  dfabulich         |      Owner:  (none)
    Type:  defect            |     Status:  new
Priority:  normal            |  Component:  Engine: SCI
 Version:                    |   Keywords:
    Game:  Gabriel Knight 1  |
-----------------------------+-------------------------
 With "Enable high resolution graphics" turned on, Gabriel Knight 1 CD
 (DOS, or Windows) renders to a 640x480 screen, so the conversation
 portraits and interface windows can be drawn at their native size. The
 320x200 low-res graphics are doubled horizontally but stretched by 12/5
 vertically, so source rows alternate between 2 and 3 pixels tall (in a 3,
 2, 3, 2, 2 pattern) instead of being a uniform 2.

 This is most visible in text, especially dialogue menus. The same glyph
 looks different depending on which row it lands on: a horizontal stroke
 can be 2 or 3 pixels thick, and lines of text don't have consistent
 spacing.

 The original interpreter has the same artifact, so this is faithful, but
 it's unpleasant.
