Re: Emacs Mac port

The third update of Emacs 24.4 Mac port 5.x is available from

    ftp://ftp.math.s.chiba-u.ac.jp/emacs/emacs-24.4-mac-5.3.tar.gz

Blend-and-blur of background color on OS X 10.10 is temporarily
disabled to avoid mode-line erasure on frame focus switch.  For some
reason, mode-line row's `enabled_p' flag in the current matrix is
sometimes reset even if it is visible.  This causes blank mode-line on
"expose" (drawRect:) events.  In principle, this mode-line erasure can
also happen on older versions of OS X or this version of Emacs Mac
port.  But it is usually observed on OS X 10.10 together with previous
5.x versions of Emacs Mac port, because the use of NSVisualEffectView,
which provides the blend-and-blur feature, triggers full frame
"exposure" on focus switch.

** Fixed bugs

*** Special-display completion frame becomes transparent.
Reported by Alan Shumitt.
Adapt a fix for Bug#16619.

*** `mac-auto-ascii-mode' on TTY terminals disables prefix keys with
the meta key.

*** Control-F2 is passed to the system even if
mac-pass-control-to-system is set to nil.

*** Synthetic bold text looks thinner on Retina display/HiDPI mode.
This is because stroke line width for text drawing is not correctly
scaled (whereas it is correctly scaled when drawn to bitmaps) on such
environments.  I've been reporting this to Apple on every OS X update
since it was 10.7.4, but I couldn't get any response until recently.
At last Apple answers that there are no plans to address this issue
(rdar://11644870) currently.  So I added a workaround that would cause
a bad reverse effect if the original issue were fixed.

*** `mac-ae-set-reply-parameter', which is used for reporting an error
in Apple event hander, has not been working since emacs-24.2-mac-3.2.

*** Input source functions ignore disabled input source ID strings.

** Improvements

*** URL handler via Apple events now accepts the `org-protocol' scheme
as well as `mailto'.
