The only way to have G_IO_ERROR_CANCELLED in the write callback
goes through having the array of pending writers already cleared.
It should not access the invalid AsyncWriteData and StoredSelection
in that case.
.osd suggests a particular color/background/hover style, while .circular
only suggests roundness. So for buttons that use both classes, make sure
the former takes precedence with regard to background/hover.
gdk_window_impl_quartz_release_context () can be called with a NULL CGContextRef. This causes CoreGraphics assertion failures when debugging a Gtk application in Xcode, as the code was blindly passing that NULL to CGContextRestoreGState () and CGContextSetAllowsAntialiasing (). Given that the matching pair of CGContextSaveGState () and CGContextSetAllowsAntialiasing () calls are already checking for a NULL CGContextRef, it seems reasonable to wrap these calls in a NULL check.
Cache separately the selection contents for each given window/selection/atom
combination, and keep the requestors separate for each of those.
This allows us to incrementally request multiple mimetypes, and dispatch
the requestors as soon as the data is up. This stored selection content is
cached until the selection owner changes, at which point all pending readers
could get their transfers cancelled, and the stored content for the selection
forgotten.
We want expander arrows to be vertically centered in their row, so we
pass the cell area's height to the renderer.
However, if the cell area's height is an odd number while the
"expander-size" style property is an even number, or vice versa, the
arrow will be centered in a half pixel, and fuzzily rendered.
So, round the render height to the same parity as the expander-size.
(This is not necessary for the arrow width because it's assumed equal
to the "expander-size" style-property.)
An expander arrows's render width is supposed to be derived from the
"expander-size" style property.
However, we are actually rendering it for a width equal to
expander-size + 1. This results in ugly blurry rendering.
There is a comment justifying this "+ 1", which has been there for
almost 2 decades. But the justification doesn't seem to apply to
the current code, so the original motivation is likely obsolete.
Let's remove this "+ 1" to render the arrow to a width exactly equal
to the "expander-size" style property.
This reverts commit d6a29e1b8c.
It fixed blurry rendering of expander arrows.
However, it also introduced a regression in that the arrows are no
longer vertically centered if rows are taller than twice the
expander-size style property.

For a given OpenGL context, macOS in particular does not support enumeration / detection of OpenGL features that have been promoted to core OpenGL functionality. It is possible other drivers are the same. This change assumes support for GL_ARB_texture_non_power_of_two with OpenGL 2.0+, GL_ARB_texture_rectangle with OpenGL 3.1+ and GL_EXT_framebuffer_blit with OpenGL 3.0+. I failed to find definitive information on whether GL_GREMEDY_frame_terminator has been promoted to OpenGL core, or whether GL_ANGLE_framebuffer_blit or GL_EXT_unpack_subimage have been promoted to core in OpenGL ES. This change results in a significant GtkGLArea performance boost on macOS.
Closes#2428
Call gtk_widget_set_allocation after chaining up to parent class
to ensure that GtkInfoBar has correct allocation. Otherwise x and y
is set to zero causing wrong window position in gtk_info_bar_realize.
This fixes info-bar-message-types.ui reftest.

Epiphany is doing something weird after calling gtk_window_close(),
because by the time the callback executes, the window has no GdkWindow.
Frankly, I don't know what's happening there, but we should probably not
crash.
Fixes#2424
This reverts commit ee448db031.
The `name_suffix` argument is already set, and by setting it twice we're
just getting a warning at configuration time from Meson.
link target uses `$selected_bg_color` and `$selected_fg_color` for the
definition of some selectors (e.g. selected).
While `$link_color` and `$link_visited_color` are based on
`$selected_bg_color`, this does not seem coherent.
Replacing `$selected_*g_color` in link target style with link colors
defined in `_colors.scss file`.
