When the command queue is out of batches, there is
no point in doing further work like allocating uniforms.
This helps us avoid assertions in the uniform code
that we would hit when we run out of uniform space
too.
Commit 3090795351 accidentally caused all
CI builds (or at least the ones with -Werror) to no longer build tests,
examples and demos, so none of them had made sure that they compile.
When we start ignoring batches, we must do it everywhere,
or we may run into assertions. This was triggered by an
enormous text node tree produced by tests/rendernode-create.
The documentation says that the model returned by
gtk_notebook_get_pages() implements the GtkSelectionModel interface, but
checking the history confirms this is a lie.
Instead of fixing the documentation, we can easily make it true, and
reduce the differences between GtkNotebook and GtkStack.
Fixes: #5837
If there is a value passed to GSK_RENDERER, display it in the window
title.
This is mostly so that when I show off screenshots, people know what
renderer I'm using.
Vulkan has a different initial coordinate system to GL.
GL:
(-1, 1, -1) +------+.
|`. | `.
| `·--|---·
| : | :
+------+. :
`. : `.:
`·------· (1, -1, 1)
Vulkan:
(-1, -1, 0) +------+.
|`. | `.
| `·--|---·
| : | :
+------+. :
`. : `.:
`·------· (1, 1, 1)
so adjust the near and far plane we pass to
graphene_matrix_init_ortho() to make it end up with the same
projection as the GL renderer.
This one tests a crossfade between two non-overlapping nodes with a clip
region that covers neither of the two nodes.
This tests that renderers can deal with clip regions that doesn't
overlap nodes in a situation where they will most likely want to create
an offscreen.
As offscreens are typically clipped to the clip region, this would cause
an empty offscreen and that can cause failures.
This was an experiment where an offscreen was translated inside an
existing clip.
Because renderers try to limit offscreens to the clip rect, this is
interesting, because they might get the translation wrong.
Using gdk_texture_new_from_resource() is not valid here because we are
not sure if the given resource is valid.
Plus, the previous optimization is no longer relevant, because we are
not using gdk_pixbuf_new_from_resource() anymore - which was what this
optimization was about before it was ported to GdkTexture.
Test attached.
