3e44ee5569 Call xsetenv() in main process instead of child
This makes xsetenv internal to x.c, and allows iso14755's external
command to use $WINDOWID instead of having to snprintf it again.  (The
same benefit will apply to the externalpipe patch.)  The xwinid function
is no longer needed.

ee5cc8e903 base64dec: skip non-printable characters like \r\n
Non-printable characters, such as line breaks, in a base64 encoded
string violate the "string length must be a multiple of four" rule.

This patch pads the result buffer by one extra unit of four bytes,
and skips over non-printable characters found in the input string.

fa9a459972 Fixed 'missing glyph doesn't use fontconfig config substitutions' bug
XftFontMatch does display-specific font configuration (commit 528241a).
Nice. Unfortunately, when we switched from FcFontMatch, we also stopped
storing the post-Fc{Config,Default}Substitute FcPattern for future
lookups. The result is that if a glyph isn't found in the primary font,
secondary font lookups use the original FcPattern, not the configured
one. If you have custom fontconfig rules (like me), this can be
disappointing.

I basically just copied the guts out of XftFontMatch[1] and saved
the intermediate configured FcPattern. Could be related to the bug that
inspired commit 4242027.

424202798b Initial font size issue.
Hi,

When I specify a font by point size (I'm using "Inconsolata:size=12"),
characters that are substituted from another font because they are not in the
main one appear too small.  Doing a zoom reset fixes it.  For example:

Before: http://i.imgur.com/G4Mfv4X.png
After:  http://i.imgur.com/PMDhfQA.png

I found that adding the pixel size (acquired from the initial font load) to the
pattern then reloading the font fixes the problem.  I'm not sure if this is a
proper fix, though.

902a392b90 Make strdump(), csidump(), print to stderr
The two functions strdump(), csidump() are called to show errors and
their output is introduced by a message printed to stderr. Thus, it it
more consistent to have them print to stderr.

Moreover stderr is unbuffered (at least on Linux), making problems
immediately visible.

528241aa38 Use XftFontMatch in place of FcFontMatch.
git am -s didn't like your patch:

From: Mark Edgar <medgar123@gmail.com>

XftFontMatch calls XftDefaultSubstitute which configures various match
properties according to the user's configured Xft defaults (xrdb) as well as
according to the current display and screen. Most importantly, the screen DPI
is computed [1]. Without this, st uses a "default" DPI of 75 [2].

60aeb37edb delete clipboard properties after pasting them
https://tronche.com/gui/x/icccm/sec-2.html#s-2.4 specifies:
> Once all the data in the selection has been retrieved,
> the requestor should delete the property in the SelectionNotify request

Most Clipboard-Owners ignore whether or not the property is already set,
so this is mostly a cosmetic change to keep the windows property list clean.

However, at least synergy decides to wait for the requestor to delete
the properties if they are already set by a previous paste (from synergy).

39964614b7 st: Fix off-by-one error when calculating character width.
LEN(str) is one larger than strlen(str) because it also counts the zero
terminator. The original code would include the .notdef glyph (since it'll
try to encode character 0, which gets encoded to the .notdef glyph) when
measuring the average dimensions of printable ascii characters.

This causes problems with fonts like GNU Unifont where the .notdef glyph is
not the same width as the usual half-width characters.

4be353e381 Fix extra bracketed paste markers when pasting >8kb
Before this patch, when pasting over BUFSIZE (8192 bytes here), st would
do the following:

    \e[200~...8192 bytes...\e[201~\e[200~...remaining bytes...\e[201~

With this patch, the start marker is only sent when the offset is 0 (at
the beginning of selnotify) and the end marker is only sent when the
remaining bytes to read are 0 (at the end).

For short pastes, both conditions are true in the same iteration.

For long pastes, it removes the extra markers in the middle, keeping the
intended wrapping:

    \e[200~...8192 bytes......remaining bytes...\e[201~

ae1923d275 Clean up xdraws and optimize glyph drawing with non-unit kerning values
I have another patch here for review that optimizes the performance of
glyph drawing, primarily when using non-unit kerning values, and fixes a
few other minor issues. It's dependent on the earlier patch from me that

This patch is a pretty big change to xdraws so your scrutiny is
appreciated.

As you can see, while the improvements for fonts with unit-kerning is
marginal, there's a huge ~81x performance increase with the patch when
using kerning values other than 1.0.

So what does the patch do?

The `xdraws' function would render each glyph one at a time if non-unit
kerning values were configured, and this was the primary cause of the
slow down. Xft provides a handful of functions which allow you to render
multiple characters or glyphs at time, each with a unique <x,y> position,
so it was simply a matter of massaging the data into a format that would
allow us to use one of these functions.

I've split `xdraws' up into two functions. In the first pass with
`xmakeglyphfontspecs' it will iterate over all of the glyphs in a given
row and it will build up an array of corresponding XftGlyphFontSpec
records. Much of the old logic for resolving fonts for glyphs using Xft
and fontconfig went into this function.

The second pass is done with `xrenderglyphfontspecs' which contains the
old logic for determining colors, clearing the background, and finally
rendering the array of XftGlyphFontSpec records.

There's a couple of other things that have been improved by this patch.
For instance, the UTF-32 codepoints in the Line's were being re-encoded
back into UTF-8 strings to be passed to `xdraws' which in turn would then
decode back to UTF-32 to verify that the Font contained a matching glyph
for the code point. Next, the UTF-8 string was being passed to
`XftDrawStringUtf8' which internally mallocs a scratch buffer and decodes
back to UTF-32 and does the lookup of the glyphs all over again.

This patch gets rid of all of this redundant round-trip encoding and
decoding of characters to be rendered and only looks up the glyph index
once (per font) during the font resolution phase. So this is probably
what's responsible for the marginal improvements seen when kerning values
are kept to 1.0.

I imagine there are other performance improvements here too, not seen in
the above benchmarks, if the user has lots of non-ASCII code plane characters
on the screen, or several different fonts are being utilized during
screen redraw.

Anyway, if you see any problems, please let me know and I can fix them.

c990abfedf Fix empty selection highlighting bug.
When user clicks LMB, one character is selected, but will not be copied
to selection until the user moves cursor a bit. Therefore, the character
should not be highlighted as selected yet.

Before the patch, the trick was not to mark line as dirty to avoid
highlighting it. However, if user has already selected something and
clicks in line that contains selection, selclear sets the line as dirty
and one character is highlighted when it should not.

This patch replaces dirty trick with explicit check for sel.mode inside
selected().
