This allows the compositor to avoid having to setup and teardown a
SIGBUS signal handler whenever it needs to read from this surface, as it
knows we won’t be able to shrink the file and so doesn’t have to protect
against that.
This codepath will only be used on Linux ≥ 3.17 with glibc ≥ 2.27, and
possibly other kernels and libc. The former code will continue to be
used as a fallback, either if memfd_create() fails or if it isn’t
available.
This adds the GLFW_SCALE_TO_MONITOR window hint for automatically
resizing the content area of a window to the requested size times the
monitor content scale each time it is placed on a new monitor. This
only applies to windowed mode windows and includes the initial placement
at window creation.
This hint only has an effect on platforms where screen coordinates and
pixels always map 1:1 such as Windows and X11. Platforms like macOS
instead change the resolution of the framebuffer independently of the
window size.

This adds basic support for the Per-Monitor V2 level of DPI awareness
in Windows 10, which allows for automatic DPI scaling of window
decorations.
This commit does not include resizing the window content area to match
the new window content scale.

Fixes#1294.
When mouse trails are enabled, the cursor becomes invisible when the
OpenGL ICD detects a full screen window and switches to page flipping.
Mouse trails are now disabled as long as any full screen windows are
visible.
Fixes#1263.
This adds a window hint and attribute for controlling whether
glfwShowWindow gives the specified window input focus in addition to
making it visible.
Fixes#1189.
Closes#1275.
In 32e78aeb2 the definition of DWM_BLURBEHIND in win32_platform.h was
moved behind a WINVER < 0x0600 preprocessor check (< Vista). This broke
the build for WINVER >= 0x0600 since DWM_BLURBEHIND is not defined.
Starting with Vista DWM_BLURBEHIND is available in Dwmapi.h.
So we can just include the header directly on Vista and above.
Closes#1253.
