The lpClass parameter isn't used, and it is valid to pass NULL for it.
It is, however, not valid to pass a string literal, because the
conversion to nonconst char* has been deprecated in C++ for a long time
and doesn't exist anymore in C++11.
If the gamepad code initialized the SDL video subsystem, GTK+ crashed in
libX11. Or something along those lines.
Making the optional subsystems using SDL for gamepads and audio use
SDL_InitSubSystem and only the SDL Application port do the full SDL_Init
is the proper way to do things in any case.
The GTK and OS X platforms already ignored the requested bit depth and
always used 32 bit. Windows and SDL would set a 16 bit color depth for
the screen, but still did all of the rendering short of the final
present in 32 bit.
Even though we (might) change the resolution, that doesn't result in
loss of textures because we don't recreate the OpenGL context. Therefore
we also don't have to restore their data. I believe this code is a relic
from the DirectX renderer, which would lose textures when switching away
from a fullscreen window.
USE_WIN32_WINDOWS was previously defined in PlatformAbstraction.h. Move it
to CMakeLists.txt and config.h like its peers. Replace USE_X11 with USE_GTK
or GDK_WINDOWING_X11 as appropriate.
For example, keydown events when pressing/releasing the shift, alt, or control
keys. With this version this is needed ingame e.g. to pick up objects with
Shift.
Specifically, GtkGrid. For most cases, this is an increase in lines of
code, but the landscape tools dialog can now be done with just three layout
widgets.
While at it, use a toolbar and move the mode buttons into it, too.
In order to avoid duplication, PlatformAbstraction.h has to be included at
the start of every source file, so that various headers can rely on it
being there. To avoid confusion, always rely on that, instead of sometimes
randomly including it or parts of it again.
Video recording and playback only worked on Windows, and recording only
handled video, not game audio. As such, it was of fairly limited use,
and there's lots of software available these days that handle both.
It's still pretty useless because nobody cares in the slightest about
which extensions are available and which ones aren't, but at least now
it doesn't throw an unintelligible list of numbers at you.
Hardly anyone ever tests the headless build, because it requires you to
run CMake a second time with -DUSE_CONSOLE=On. So now it's an included
project which you'll get whether you want it or not.
I'm well aware that this could be solved more nicely, and that we could
be splitting unchanged files out into a separate support library, but
that's left for a later date.
A playlist change would reset SCounter and eventually cause all songs to be non-eligable.
Since playlists can now select differently sized subsets, the old way of selecting random songs without too much repetition no longer works. Rewrite to use a more robust algorithm.
Pressing the Alt key enters the menu modal loop, which takes control of
the thread that everything happens on. As a quick fix, we'll suppress
this loop for simple Alt key presses, but this will still happen when
the system menu gets opened by Alt+Space or clicking the icon in the
window's title bar.
A more permanent solution would be to detach the message loop from
everything else, by having rendering etc. run in a separate background
thread.
The C++ standard library comes with perfectly fine implementations of
these functions, so there's no point in reimplementing them just for the
hell of it.
