fiddlerwoaroof/crawl - Change EOMCPVNQLX3IMLC46EAO67DPBH5KEG2FQTPBLGU62HIRWA3UQ7XQC

[1699948] Allow changing the viewport size if you're using a larger terminal

than 80x24. Also allow moving the PC around the viewport without scrolling the viewport if the viewport is large enough.

This is not tested on DOS and Windows yet.

The viewport is the portion of the map that is displayed during normal
play. The viewport is 33x17 by default, but if you use larger terminal
sizes, you can set these options to make the game show a larger
viewport. (These options are not fully available on DOS.)
None of these options affects gameplay. In particular, your character's
line-of-sight is unaffected by these options.
view_max_width = 33
        Sets the maximum width of the viewport (defaults to 33).
        Making this larger will allow Crawl to show a wider viewport
        on larger terminals.
view_max_height = 17
        Similar to view_max_width, but sets the viewport's maximum 
        height.
* Note that using large viewports can slow the game down.
view_lock_x = true
        Keeps the player character centered horizontally in the
        viewport, continuously scrolling the viewport to match the
        PC's movements. If this is not set, the player character can
        move horizontally within the viewport, and the viewport will
        scroll only when the character's line-of-sight reaches the
        left or right edge.
view_lock_y = true
        Keeps the character centered vertically in the viewport.
view_lock = true
        Aliased option that sets both view_lock_x and view_lock_y.
center_on_scroll = false
        If this is set, the viewport centers on the player character
        whenever it scrolls (this option is irrelevant if view_lock_x
        and view_lock_y are set).
symmetric_scroll = true
        If this is set, the viewport will scroll in a manner consistent
        with the character movement that caused the scroll.
        To illustrate, let's say the PC is at the lower edge of the
        viewport, but is near the horizontal center. Now the PC moves
        diagonally down and right, forcing the viewport to scroll up
        one line. If symmetric_scroll is set, the viewport will also
        scroll left one column to match the PC's diagonal movement. If
        symmetric_scroll is not set, the viewport will only scroll up,
        not horizontally. symmetric_scroll can be less disorienting
        than free scrolling.
        This option is not relevant if view_lock or center_on_scroll
        are set.
scroll_margin_x = 4
        How far from the left or right edges scrolling starts. By
        default, if the PC's circle of line-of-sight is closer than 4
        squares from the edge, the viewport scrolls. If set at zero,
        the viewport scrolls only when the LOS circle reaches the
        viewport edge.
scroll_margin_y = 4
        How far from the top or bottom edges scrolling starts.
scroll_margin = 4
        An aliased option that sets both scroll_margin_x and 
        scroll_margin_y.
