We already ceil() the given float texture sizes here, so if they are
valid, the result should definitely be > 0. Textures with size 0 can't
be properly used, especially not as render targets, where they will
trigger an assertion failure later in a glCheckFramebuffer call.

ddb77d6c9b GskGLDriver: Use float for texture size in create_texture 
Render nodes can end up with bounds < 1 since they are floats, and the
implicit cast to int ends up creating a texture with 0 width or height.
Use ceil() instead in create_texture so we don't have to do that on the
caller side everywhere.

8993a51893 vulkan: Destroy buffer before releasing associate memory

Georges Basile Stavracas Neto
147a455171 vulkan: Destroy image before releasing associate memory 
VkImage contains a reference to the VkDeviceMemory and, because
the current code frees the VkDeviceMemory before destroying the
VkImage that references it, a warning is triggered by the validation
layers.

This is not critical, since we release both resources at the same
place. But the warning triggered by the validation layers sums up
adding 1 MB per second of extra debug logging, making the debugging
process much more painful.

This commit simply swaps the destruction order, and destroys the
VkImage first, then the now unused VkDeviceMemory.

bd287ba3cf renderer: Assert having been unrealized in dispose 
We cannot unrealize a renderer in the dispose function, because that
would cause this chain to happen:
  gsk_gl_renderer_dispose
  gsk_renderer_dispose
  gsk_renderer_unrealize
  gsk_gl_renderer_unrealize
So we would call into thje GL renderers unrealize when it has already
(partially) disposed itself and ause accesses to dead variables.

a0bbd14325 gsk: Scale glyphs in the glyph cache 
Pass a scale factor when caching glyphs or looking them

43c212ac28 build: Enable -Wswitch-enum and -Wswitch-default 
This patch makes that work using 1 of 2 options:

1. Add all missing enums to the switch statement
  or
2. Cast the switch argument to a uint to avoid having to do that (mostly
   for GdkEventType).

I even found a bug while doing that: clearing a GtkImage with a surface
did not notify thae surface property.

The reason for enabling this flag even though it is tedious at times is
that it is very useful when adding values to an enum, because it makes
GTK immediately warn about all the switch statements where this enum is
relevant.
And I expect changes to enums to be frequent during the GTK4 development
cycle.

3aaea0ef40 Clip intermediate textures 
In some cases, we were creating gigantic intermediate textures
only to clip out a small section afterwards (e.g. in the listbox
example in gtk4-demo). This is wasteful if we apply effects on
the texture, such as blur or color-matrix. So, clip the dimensions
of the intermediate texture with the current clip. To make this
feasible, we move the texture coordinate computation out of the
pipeline setup functions into the node_as_texture function where
this clipping happens.

One extra complication we encounter is that the node might get
clipped away completely. Since Vulkan does not allow to create
empty images, we bail out in this case and not draw anything.

With these changes, the listbox example in gtk4-demo goes from
32M pixels of intermediate texture to 320000.

b0e8d8483d More work on text nodes 
This commit takes several steps towards rendering text
like we want to.

The creation of the cairo surface and texture is moved
to the backend (in GskVulkanRenderer). We add a mask
shader that is used in the next text pipeline to use
the texture as a mask, like cairo_mask_surface does.
There is a separate color text pipeline that uses the
already existing blend shaders to use the texture as
a source, like cairo_paint does.

The text node api is simplified to have just a single
offset, which determines the left end of the text baseline,
like all our other text drawing APIs.

4975aa7920 Add a render node for text 
This is just a wrapper around a PangoGlyphString + PangoFont.
Basically, the arguments that are passed to pango_renderer_draw_glyphs.

48df19287b gsk: vulkan: fix image uploading 
The memory alignment requirements are different from the image layout.
We want the rowPitch to know where to upload the lines.

4904491b77 build: Move Vulkan shader handling to its own directory 
Spooky action at a distance is not really allowed in Meson, so the rules
to generate the SPV files should go in their own directory.

6728f45aa0 build: Ensure that Vulkan shaders are rebuilt if glslc is found 
If glslc is found, rebuild the shaders from GLSL to SPIR-V; otherwise,
we're just going to use the built files we have committed in the source
repository.

e850973956 meson: build input modules 
We have to work around some ordering problems here. We still
manage to keep most of the guts in modules/input/meson.build,
so it's not too ugly overall.

(The autotools build solves this with a 'make -C ../../input/modules'
inside gtk/Makefile, but that's not something we can or want to do.)

f67a9d58db meson: make sure gsk/gdk generated headers exist for libgtk_dep users 
Add back dependencies on libgdk_dep and libsk_dep which are declared
dependencies. We removed this before because these declarations had
link_with: lines that dragged in the static libgdk.a and libgsk.a libs
which are linked into libgtk-4.so anyway and thus shouldn't be used
when linking internal exes/tools against libgtk-4. Remove the static
libs from the declared dependencies and have libgtk link those in
explicitly, so that the declared deps now just provide all the built
dependencies and include dirs and such for declared libgtk_dep users
such as the internal exes/tools, which want all the generated gsk/gdk/gtk
headers to exist before attempting to compile anything against the
gtk+ headers.
