This new API lets the application know when the current buffer was last
written to. If it returns 0, it means the user shouldn’t rely on what
was last present in this buffer and should draw everything again, as
usual.
This provides a significant boost in efficiency, especially on tiling
GPUs, by letting the application avoid to clear and redraw everything at
every frame.
This new API helps the user’s compositor reduce memory bandwidth and
thus power usage by only re-rendering a bunch of dirty rectangles
instead of the entire application buffer.
There is no guarantee that it will effectively get used, it is perfectly
valid to continue damaging the entire buffer instead like with
glfwSwapBuffers() in some cases.
When both GLFW_INCLUDE_VULKAN and VK_USE_PLATFORM_WIN32_KHR were
defined, the GLFW header would define replacement versions of APIENTRY
and WINGDIAPI /before/ including the Vulkan header, which would include
windows.h, which (justifiably) defines APIENTRY and WINGDIAPI blindly.
Fixes#1524.
Most context related hint and attribute links had copypaste errors.
The GLFW_CONTEXT_RELEASE_BEHAVIOR and GLFW_CONTEXT_NO_ERROR attributes
did not have guide documentation.
This protocol is part of the core Wayland, but it is pretty badly
designed and is missing quite a few features, and is in the process of
being phased out in compositors. Its support in GLFW requires
duplicating pretty much every single window management codepath.
This bumps the required compositor versions to the ones which have
implemented xdg-shell, approximately two years ago, which seems sensible
to me.
This renames 'raw input' to 'raw mouse motion' as there are other kinds
of raw input. The update path is restructured to avoid reinitializing
all of disabled cursor mode. Modification of shared state is moved out
into shared code. Raw mouse motion is disabled by default for
compatibility.

This makes glfwSetGamma generate a gamma ramp of the same size as the
monitor's current ramp, which will avoid failure on non-256 entry
monitors on X11 and avoid ramp interpolation on macOS.
Closes#1387.
Fixes#1388.
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 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.
OpenGL / OpenGL ES cannot share presentation on a window with Vulkan.
This adds an error to `glfwCreateWindowSurface` when it is called on a
window without the GLFW_CLIENT_API hint set to GLFW_NO_API. This
prevents undefined bahevior and hard to debug crashes.
Fixes#1194.
Closes#1205.
