Dragging will just drag the render node.
Dropping will replace the current contents of the textview with the
dropped node.
Neat side effect: You can drag the node onto itself to do a
deserialize/serialize of the current text.
The font sizes demo had the space between the font-size spans,
causing us to have a run with just a default sized space between
the words, which in turn leads to wobbly cursor sizes. Avoid that
by including the space in the preceding span.
Also, make it bigger.
Update all the places where we switch over
PangoAttrType to handle PANGO_ATTR_TEXT_TRANSFORM,
and do nothing for now - text-transform support
will land in 4.6.
The old code was just pasting local clipboard data that we put there
ourselves and was causing criticals on remote clipboard data. Now the
code does the proper async paste.
Instead of havoing a label for the video frame that clashes with the
background of the video, add a frame around the text styles box and add
a label for them. As a side benefit, it also makes it more obvious that
it is scrollable.
Note: Most of this patch is just reindenting.
Also rename gtk_media_stream_ended to
gtk_media_stream_set_ended, to avoid naming
collision with GtkMediaStream:ended.
The existing entry points still exist, deprecated
and marked as non-introspectable.
Update all internal uses.
Fixes: #4023
Some bindings can't handle the coexistence of
GtkMediaStream:prepared and gtk_media_stream_prepared.
Help them out by renaming the function to
gtk_media_stream_set_prepared, and rename
gtk_media_stream_unprepared as well, to match.
The existing entry points still exist, deprecated.
Update all internal uses.

The script assumes that the git program is in the PATH which may not be always
the case, so if git was not found, fallback to the former behavior of making
VCS_TAG an empty string if the profile option was not set to 'devel'.
Also fix the call to the script so that we do indeed call GIT on the source GIT
repo so that we can get the right short SHA1 sum.
Re-organize the code a bit in the process, so that things seem cleaner.
The CI pipeline does not do a full clone, so we cannot use `git
rev-parse` to get the short SHA checksum for the current commit.
Of course, since nothing's ever easy, we cannot use vcs_tag() with a
custom command, so we need to generate our out `demo_conf.h` header
straight from a script.
gcc says: error: iteration 2147483649 invokes undefined behavior
[-Werror=aggressive-loop-optimizations]
which of course, never happens because ncols is always >= 2.
Add some assertions to tell the compiler.
The primary goal here was to cleanup the current GL renderer to make
maintenance easier going forward. Furthermore, it tracks state to allow
us to implement more advanced renderer features going forward.
Reordering
This renderer will reorder batches by render target to reduce the number
of times render targets are changed.
In the future, we could also reorder by program within the render target
if we can determine that vertices do not overlap.
Uniform Snapshots
To allow for reordering of batches all uniforms need to be tracked for
the programs. This allows us to create the full uniform state when the
batch has been moved into a new position.
Some care was taken as it can be performance sensitive.
Attachment Snapshots
Similar to uniform snapshots, we need to know all of the texture
attachments so that we can rebind them when necessary.
Render Jobs
To help isolate the process of creating GL commands from the renderer
abstraction a render job abstraction was added. This could be extended
in the future if we decided to do tiling.
Command Queue
Render jobs create batches using the command queue. The command queue
will snapshot uniform and attachment state so that it can reorder
batches right before executing them.
Currently, the only reordering done is to ensure that we only visit
each render target once. We could extend this by tracking vertices,
attachments, and others.
This code currently uses an inline array helper to reduce overhead
from GArray which was showing up on profiles. It could be changed to
use GdkArray without too much work, but had roughly double the
instructions. Cycle counts have not yet been determined.
GLSL Programs
This was simplified to use XMACROS so that we can just extend one file
(gskglprograms.defs) instead of multiple places. The programs are added
as fields in the driver for easy access.
Driver
The driver manages textures, render targets, access to atlases,
programs, and more. There is one driver per display, by using the
shared GL context.
Some work could be done here to batch uploads so that we make fewer
calls to upload when sending icon theme data to the GPU. We'd need
to keep a copy of the atlas data for such purposes.
The demo is called 'Video', so we should actually
use a GtkVideo widget. Doing things this way has
the advantage that we get GL support, which wasn't
working with GtkPicture.
According to OpenGL spec, a shader object will only be flagged
for deletion unless it has been detached; when a program object
is deleted, those shader objects attached to it will be detached
but not deleted unless they have already been flagged for deletion.
So we shall detach a shader object before it is deleted, and delete
it before the program object is deleted best.
1. That's a bad idea UI wise as you can't see the search after you
scrolled.
2. That's a bad idea code-wise because Listviews need to be put into
a ScrolledWindow or they won't scroll.
This commit changes the behavior of window size computation and the
default size properties to:
* The default-width and default-height properties are updated to the
current window size unless the size is fixed by e.g. being maxmized,
tiled etc.
* The compute-size semantics are to just pick the default size, or if
not adequate, use the measured size, and consequently update the
default size, unless unresizable.
* gtk_window_get_size() is removed, what's more likely relevant is the
gtk_window_get_default_size() which will now contain more sensible
values.
Various places that used gtk_window_get_size() were updated to use
gtk_window_get_default_size() to remember and restore previous sizes.
This also changes the default value of 'default-width' and
'default-height' from -1 to 0. The gtk builder simplify tool is taught
how to omit when the default size is set to both -1 and 0.
