On Windows 7, when GLFW framebuffer transparency and the DWM are enabled
but DWM transparency is disabled (i.e. when the Transparency setting is
disabled under Personalization > Color), the contents of the framebuffer
is combined with the last frame using additive blending instead of
replacing the previous contents.
This commit limits GLFW framebuffer transparency on Windows 7 to when
DWM transparency is enabled, removing the previous workaround of setting
a layered window color key that led to rendering artifacts.
Fixes#1512.
This makes joystick support initialize the first time a joystick
function is called, including those gamepad functions that are layered
on top of joystick functions.

Background: The IM will filter out key events, instead sending exact
duplicate events that are not filtered. It does not send these for
every event, however, so the duplicate events cannot be relied on for
key input. Instead we need to identify and discard them. Since they
are identical, they have the same timestamp as the originals.
The previous duplicate event detection would consume unrelated key
events if the keys were pressed simultaneously, as it only tracked
a single timestamp.
This fixes that issue for any combination of keys, at the expense of
a 1 KB array per GLFW window.
This fix is a stopgap until explicit IME support is done.
Based on #1472 by @LucaRood.

Closes#1472.
This adds support for EGL_EXT_platform_base and its associated X11 and
Wayland extensions, allowing us to explicitly tell EGL which window
system we are using.
This is based on work by @linkmauve in #1691.
Closes#1691.
This fixes a race between the key repeat logic and the surface leave
event handler, which could result in repeated keys being reported with
a window of NULL.
Fixes#1704.
The documentation claims that any extension loader library header
included before the GLFW one will prevent the inclusion of the
default OpenGL header. In reality this only worked if the loader
defined the canonical desktop OpenGL __gl_h_ inclusion guard and even
then relied on the OpenGL header to detect this.
This is the companion to 105cf32e0b, which
added the preprocessor logic to check for many known OpenGL and OpenGL
ES inclusion guards and not even attempt to include the default header
if any are present.
Some clarification of the language around header inclusion has also been
attempted, including making GLFW_INCLUDE_NONE more prominent.
Fixes#1695.
This adds two new error codes: GLFW_FEATURE_UNAVAILABLE for when
a GLFW feature cannot be reasonably implemented on that platform, and
GLFW_FEATURE_UNIMPLEMENTED for when it can be but has not been yet.
This replaces the current situation where the Wayland code emitted
GLFW_PLATFORM_ERROR in both cases while the macOS code silently did
nothing.
If your application exits on any GLFW error, these error codes should at
least be easy to filter out from that behavior.
Ideally, GLFW_FEATURE_UNAVAILABLE should be rare and
GLFW_FEATURE_UNIMPLEMENTED should never be emitted at all.
Fixes#1692.
The only two EGL implementations on macOS are Swiftshader and ANGLE.
While Swiftshader supports both `NSView` and `CALayer` as
`EGLNativeWindowType`, ANGLE supports only `CALayer`. Furthermore
Swiftshader's OpenGL ES frontend is deprecated in favor of using ANGLE's
Vulkan backend on top of Swiftshader's Vulkan frontend.
This means that on macOS `EGLNativeWindowType` should be a `CALayer` for
compatibility with ANGLE.
Fixes#1169.
Closes#1680.
The non-root parent window owned by the WM could be destroyed before we
process the ConfigureNotify event using the cached parent handle.
Bug was found by unmapping a decorated window.
This like all uses of the Xlib error handler is not thread safe and
there is nothing we can do about that short of moving to XCB.
Fixes#1633.
This adds support for the XIM instantiate and destroy callbacks, letting
GLFW detect both when the current input method disappears and when a new
one is started.
Tested with ibus.
This moves the remaining bits of NSApplication initialization into
_glfwPlatformInit. As a side-effect of this, any command-line program
initializing GLFW will get a menu bar, which is not ideal.
If this has happened to you and a bisect led you here, please see the
GLFW_COCOA_MENUBAR init hint introduced in GLFW 3.3.
If this patch is a terrible idea, please get in touch in the 3.4 release
timeframe.
This is a replacement for 6e6805000a,
which attempts to preserve the existing menu bar creation behavior for
the 3.3-stable branch.
Fixes#1649.
This removes most references to GLU, replaces the legacy CMake cache
variables for OpenGL with the modern namespaced target and switches to
$() for command substitution.
Fixes#1580.
Some synthetic key messages come with a scancode of zero, causing them
to be translate to GLFW_KEY_UNKNOWN. This fills in the missing scancode
by translating the provided virtual key.
Rather than further complicate a single-use function, its body is merged
into the key message handler.
Fixes#1623.
The Win+V hotkey brings up a clipboard history IME that consumes the key
release. This adds left and right Super to the modifier keys manually
polled for undetected release during event processing.
Fixes#1622.
If the application is not linked against the Vulkan loader and relies on
a third-party loader library or glfwGetInstanceProcAddress, then our
call to dlopen will fail without a custom dyld environment variable.
This adds a fallback of looking in the directory of the main executable,
which matches the bundle structure recommended by the Vulkan SDK, making
that finally work out of the box for fully dynamic loading.
When the WM does not support EWMH or there is no WM running, GLFW falls
back to XSetInputFocus, which will emit BadMatch if the window is not
viewable, which will terminate the program.
Bug spotted on IRC.
A window resize action that also resulting in the window being moved did
not emit any window positions events, as the position of real
ConfigureNotify events was ignored. The real events use parent
coordinates instead of root coordinates so this adds parent tracking and
conditional translation.
Fixes#1613.
This removes the final dependency on CoreVideo, using a display link to
get the refresh rate of monitors where Core Graphics report a refresh
rate of zero. Instead we now query the I/O registry directly, similarly
to what the display link does at creation.
Thanks to @OneSadCookie for pointers to this solution.
CLOCK_MONOTONIC should not be used as a feature macro. The POSIX
feature macros are provided by unistd.h. CLOCK_MONOTONIC is provided by
time.h. CLOCK_MONOTONIC requires _POSIX_C_SOURCE >= 199309L on some
systems.
