Subject: Improved image rendering: fix max-height
X-Git-Tag: v3.2.2~7
X-Git-Url: https://thelambdalab.xyz/gitweb/index.cgi?a=commitdiff_plain;h=7e6b71d0cf4ccf5d94a95c58fc35ebf2fd09920b;p=elpher.git

Improved image rendering: fix max-height

window-pixel-height's return value includes the mode line and header
line and the bottom divider, if any. In order for the image to fit
exactly, we therefore subtract window-header-line-height,
window-mode-line-height window, window-scroll-bar-height window, and
window-bottom-divider-width.
