With maximized windows, unexpected behaviour occured when the program
resized itself, then the window manager minimized/restored the window
Should address SF bugs #18 and #13

Make an exception for all keypad stuff.

There are a number of conio changes in here too... too many to list.  Check
the diffs if you actually want to know what changed.

May fix https://sf.net/p/syncterm/tickets/19/

a new texture with the same address as a destroyed texture causes crashes.
Just allocate the new texture before freeing the old one to prevent that
from occuring.

These allow setting the initial window size for modes that don't force
integer scaling (ie: SDL).

While we're here, clear a renderer before free()ing the texture to prevent
crashing on some nVidia cards.

There's still some shittiness with the keypad, but nobody really knows how
that works anyway.

number to the remote.
Fixes bug https://sourceforge.net/p/syncterm/tickets/15/

Add support for scroll "buttons" (buttons 4 and 5).

This fixes some input weirdness with C64 mode (and likely others)

semaphores sometomes have odd behaviour... just use the same mutexes and
semaphores as everywhere else.

The SDL wiki lists KMOD_MODE as AltGR... if that flag is flying in a
keypress, do not block text input.

change the window size and it should work out alright.

anything that doesn't print is "fine".

getcliptext() and copytext() (ie: copy/paste) now work on UTF-8 strings.
Not tested on Win32 yet.

This is planned to work with the built-in fonts... no real idea how to
make this work with dynamic fonts at this time.

We'll also need a line drawing set thing ala curses, but I'll worry about
that when/if I update uifc32 for unicode.

*may* break all sorts of other things.

a major regression for key input. :(

Hopefully this fixes the issue Ragnorok was reporting with a Spanish
keyboard.

(successive beeps currently still will)

Derp.

Add UTF-8 copy/paste support to X11 mode.

Win32 can no longer exit() and WinExec() itself with impunity.
