The destination rectangle passed to SDL_BlitSurface() and SDL_BlitSurfaceScaled() is non-const and filled in with the final destination rectangle after clipping, and now documented as such.

This reverts commit 55c3c1b05c.
It turns out many Linux distributions are shipping zenity which doesn't support the new --icon option. We'll need a more robust fix for this.
On platforms where time_t is a signed 32-bit integer, most notably i386 Linux,
various functions stop working when dealing with a timestamp
beyond January 2038.
glibc has an opt-in mechanism that redefines time_t to be 64-bit,
and correspondingly increases the size of all system data
structures that contain a time_t, such as struct timeval and struct stat.
This is necessary to allow timestamps beyond January 2038 to be represented;
as well as things that obviously deal with timestamps, this affects functions
like stat(), which will fail with EOVERFLOW if asked to inspect a file whose
correct timestamp does not fit in time_t. This in turn can cause unexpected
problems for "filesystem APIs" of the form "if /run/foo exists, then ..."
when accessed by 32-bit code, if the check for existence is done with stat()
rather than access().
Using 64-bit timestamps in glibc is an opt-in and not the default, because
if done carelessly it can change libraries' ABIs. However, SDL mostly doesn't
use system headers or types in its own headers. I

On 32-bit platforms such as i386, if SDL is compiled with -D_TIME_BITS=64
to opt-in to ABIs that will not stop working in 2038, the fields in
this struct change their naming and interpretation.
The Linux header <linux/input.h> defines macros input_event_sec and
input_event_usec which resolve to the right struct field to look at.
The actual field names and types are an implementation detail,
historically signed 32-bit time.tv_sec and time.tv_usec on 32-bit
platforms, but becoming unsigned __sec and __usec when using 64-bit
time (which makes them able to represent times up to 2106).

Add a DBus message handler to watch and respond to changes to the system cursor size and theme properties. Upon these settings being changed, a cursor refresh will be triggered so the new changes will take effect immediately, without the cursor having to leave and re-enter the window surface.
Applications that don't specify a rendering flag are likely handling Vulkan/GL themselves, so SDL loading OpenGL by default in this case is unnecessary overhead, and if a render backend requires it, the window will be recreated with the appropriate flags when the renderer is initialized.
