For waveOutOpen and friend functions

.. so it can be loaded in the same solution as the conio project

to differentiate it from the non-SDL version of the conio property sheet

This allows directly setting bright foreground and background colours
rather than using bold and blink to indirectly modify them.

These do not have an effect if the desired mode is not possible
(ie: no bright background, no bright foreground).

For example, if it was set to 0.4, the initial scaling would be set
to take at most 40% of the screen height or width (whichever is
smaller) with a minimum of 1.0

There's a few ASCII control codes that need to be translated, so
add a new mapping function that tries the map first, then returns
ASCII on failure to map.

Fixes inability to use ATASCII in curses mode.

Previously, both the shift key, and the "implied shift" from CAPS
were treated as a higher priority than the CTRL modifier.  With
this change, only the explicit shift key has priority, and the
implicit one is only checked after CTRL is checked.

Fixes SourceForge bug 117

I don't believe them, but I'll fix it anyway.

Should fix ASan "crash".

This reverts commit 0a6fdb95.

This simply caused the callback to never be called.

Check size of X11 property before dereferencing as an Atom.
This fixes:

But I'm not clear when nitems_return (nir) might represent > 8-bit items or how
to detect that, so perhaps there's a *better* fix?

The commit just the zero-length behaviour from uninitialized use
with possible undefined behaviour to guaranteed undefined behaviour.

It's unlikely this is what Digitalman reported from ASan and UBSan

Fix multiple warning: ignoring return value of ‘asprintf’
    declared with attribute ‘warn_unused_result’

This was really just a test to make sure I had Geany successfully reconfigured
to no longer auto-strip trailing whitespace. Spoiler: It wasn't.

left shift of 255 by 24 places cannot be represented in type 'int'

This reverts commit e61a1aa6.

It turns out neither platform this targeted actually set that
variable correctly.

It appears that XDG_ENVIRONMENT_TYPE will always equal "wayland"
when XWayland is in use, so when we see that, switch to CLIPBOARD
instead of PRIMARY.  This should fix WSL and ChromeOS, and be
irritating on GNOME, so it's a win all around.

Still be sure to check the return value of write() though.

The return value of x11_event() isn't actually checked anywhere currently, but
still Deuce might want to adjust the new return value here (__LINE__ or -1?).

Some indicental trailing whitespace was auto-cleaned up part of this commit.
Unexpected as I thought this code had been uncrustified already.

Fixes recent regression with scfg

Because bitmap_get_scaled_win_size() was being clamped to maxsize,
no matter how much mult was incremented, w and h would never be
larger than maxwidth/maxheight and only under exceptional
circumstances would the be equal, which would result in an infinite
loop.

While we're here, set the integer scaling value so we're not chasing
ulps all over the place with floating point math/scaling when we
don't need to.

None of these were even theoretically possible on any platform, but
I took the opportunity to add bounds checking to bitmap_puttext(),
so that's good I guess.

Add some malloc() return checks, comment fall-throughs, and resolve
a sleep while holding lock.

None of these should actually matter, so hopefully I didn't add a
new bug.

- Support LCF (Last Column Flag) mode per DEC STD-070
  (Despite years of protest that it's stupid)
- "Properly" support CSI 7 m and CSI 27 m
  Now, when in "Negative Image" mode, changes to the foreground
  change how the background is drawn and vice-versa.  Perviously
  this command just swapped the two values and called it good.

Fix bad and poor unicode mappings, add support for sending Insert
and Pipe.

Save the window position and size when we enter fullscreen, and
restore when we leave... this was a bigger box of worms than
expected since we can get ConfigureNotify events that tell is
"Something" changed, but not be able to know the current window
position.

Just remove the x_get_window_info() and anything else that cares
about the window position and derive it from the ALT-Enter keypress
instead.

At the same time, try to remove as much special-casing for
fullscreen as possible.

Tested under marco and xfwm4... will test under Sommelier "soon"
