Add a blend mode to the draw command, so it can draw transparent
black. This will be used to erase the area on top of a subsurface
when we do passthrough.
Add an extra argument to pass offload info to the diffing code.
This is then used for diffing subsurface nodes differently,
depending on their offloading status.
Make sure all our dmabuf debug messages are display-scoped so the
inspector doesn't trigger them, use the same formatting throughout,
and improve consistency of wording here and there.
It started out as busywork, but it does many separate things. If I could
start over, I'd take them apart into multiple commits:
1. Remove G_ENABLE_DEBUG around GDK_DEBUG_*() calls
This is not needed at all, the calls themselves take care of it.
2. Remove G_ENABLE_DEBUG around profiling code
This now enables profiling support in release builds.
3. Stop poking _gdk_debug_flags and use GDK_DEBUG_CHECK()
This was old code that was never updated.
4. Make !G_ENABLE_DEBUG turn off GDK_DEBUG_CHECK()
The code used to
#define GDK_DEBUG_CHECK(...) false
#define GDK_DEBUG(...)
which would compile away all the code inside those macros. This
means a lot of variable definitions and debug utility functions
would suddenly no longer be used and cause compiler errors.
Drawing a texture-scale node like a texture node when the filter is set
to "linear" doesn't work, because the texture node switches to
trilinear when mipmaps are available.
There is no reason not check the alpha swizzle for being different
from its default value. I am thinking about implementing RGBx
upload with a swizzle of rgb1, and that would break here.
We just poking at display members here, there is no guarantee that
dmabuf formats have been initialized. So do it explicitly.
This prevents a crash in the inspector when viewing a recorded frame
containing a dmabuf texture, since the inspector uses a separate
display connection.
When we are running under GLES, we can use GL_TEXTURE_EXTERNAL_OES
to support YUV formats.
Since we don't want to deal with the combinatorial explosion of
compiling all our shaders with all combinations of sampler2D vs
samplerExternalOES for all their textures, we copy the external
textures to a regular texture before using them.
This shader uses samplerExternalOES to sample an external texture
and blit it into a 'normal' texture. It only works in GLES, but
we won't use it outside of GLES.
Allow our shaders to use samplerExternalOES, by declaring
that we use the relevant extension. Unfortunately, this
only works for gles, and requires different extensions for
gles2 and gles3. Yay
Add a GSK_GL_DEFINE_PROGRAM_NO_CLIP, which is like
GSK_GL_DEFINE_PROGRAM but compiles the shader just once,
with NO_CLIP defined.
This will be used in the future for shaders that do
texture conversion.
Prepare the plumbing in the GL renderer for textures that use
target GL_TEXTURE_EXTERNAL_OES. These need to use a special sampler,
so make sure our sampler machinery does not run over it.
This is a simple helper that feed a GdkTexture
through a renderer and returns the resulting
texture. This will be used to convert dmabuf
textures to 'native' textures.
Restore the bigendian support that was lost in b0e26873f6,
by just not using GL_BGRA with GLES on bigendian. Should be a
very rare combination, but still.
We did have 4 ordering variations of ARGB straight,
but only 3 premultiplied. Add the missing one.
Update all the places where we switch over memory formats.
The glyph and icon libaries were also checking for GLES to
decide if data needs to be transformed from BGRA to RGBA.
Use the new has_bgra getter instead.
This will probably break on bigendian, because the
GL_BGRA + GL_UNSIGNED_BYTE combination is not equivalent
to the cairo format on bigendian, but this was already
broken for the gl format information that we get from
gdk_memory_format_gl_format.
Make gdk_memory_format_gl_format take the GdkGLContext,
instead of just a gles boolean. This will let us
check for extensions that may be needed for certain
formats.
Update all callers.
This is useful for colorizing in the same fashion we do for the glyph
texture atlas. In fact, for small GdkTexture, you will end up in something
like the icon texture atlas.
The primary motivator for this optimization is to draw various glyph-like
features from VTE such as many forms of boxes, lines, arrows, etc.
We don't need to be calling type node conformity checking from the tight
loop of the renderjob. Hoist that into the private header and use that
intead through via the Class pointer.
Anything that includes gskrendernodeprivate.h will get an alternate form
of ref/unref for render nodes which does not need to do type checking on
the parameter. We can expect that things are correct within GTK itself and
this saves excessive amounts of TypeNode conformities checking.
