Instead of possibly calling wl_surface_commit() out of
GdkFrameClock::after-paint, tick the transient parent clock so ::after-paint
can be eventually run.
This ensures that the subsurface coordinates (considered part of the state
of the parent) aren't committed untimely, and guaranteed to be orderly with
the wl_subsurface-relative state.
This is a gtk-side fix for https://bugzilla.gnome.org/show_bug.cgi?id=738887
cairo_region_copy(NULL) will effectively return an empty region, as this
function is always meant to return valid memory. This however inverts the
meaning of the NULL region and results in entirely non-clickable windows.
This event might not have an action yet, but certainly accounts, and
should be triggering recognition.
This fixes a crash when attempting to drag CSD windows through touch. As
since cfaec2d2f5, gtk_gesture_single_get_current_sequence() would
rightfully return NULL if the gesture didn't enter recognition, making
event lookup fail.
We need to export the symbols so they can be used in the
inspector, but we don't really want to make this supported
public API, so keep them out of installed headers.
Store the cursor name on the cursor (rather than always using its type).
Use this when setting a cursor on a surface.
The mir server will fallback to using standard cursors from the cursor
theme if the name used is not one of those defined by mir, which is more
or less what we want to happen here in case of creating a cursor by
name.
If buffer age is undefined and the updated area is not the whole
window then we use bit-blits instead of swap-buffers to end the
frame.
This allows us to not repaint the entire window unnecessarily if
buffer_age is not supported, like e.g. with DRI2.
This moves the GDK_ALWAYS_USE_GL env var to GDK_GL=always.
It also changes GDK_DEBUG=nogl to GDK_GL=disable, as GDK_DEBUG
is really only about debug loggin.
It also adds some completely new flags:
software-draw-gl:
Always use software fallback for drawing gl content to a cairo_t.
This disables the fastpaths that exist for drawing directly to
a window and instead reads back the pixels into a cairo image
surface.
software-draw-surface:
Always use software fallback for drawing cairo surfaces onto a
gl-using window. This disables e.g. texture-from-pixmap on X11.
software-draw:
Enables both the above.
The Mir backend was checking for button mask changes to generate the appropriate
GDK event. When Mir generates a touch event it has no button mask. In this case
we'll just generate a primary button event.
