@Rohitth007 See my feedback in the stream, but I'm essentially interested in whether we should scale the height based on the width, or treat it differently based on another rule.

This commit is a contribution towards zulip#1005, allowing popups such as the help menu to show properly on an 80-column width terminal. This changes the fixed scaling factor of 3/4 to one that is linear in the range 80 - 100 column width: * The scaling fraction increases from 3/4 to 1 (full-width) as the available size increases from 80 to 100. This increases the range of sizes for which the popup is rendered properly. * For width's smaller than 80 it defaults to full width. * For width's greater than 100 it defaults to 3/4. The values 80 and 100 are given by: * MIN_SUPPORTED_POPUP_WIDTH = 80 * MAX_LINEAR_SCALING_WIDTH = 100 The popup height has a fixed scaling factor of 3/4, which retains visibility of the title when the window is at the minimum supported height. Tests added.

This commit is a step towards solving #1005 especially the first
2 points. This changes the fixed scaling fraction of 3/4 to one that
is linear in the range 80 - 100 column width:
available size increases from 80 to 100. This increases the range of
sizes for which the popup is rendered properly.
The values 80 and 100 are given by:
The popup height has a fixed scaling factor of 2/3.
