- Update to version 2.72.0
This is a major release with several key additions, most notably
being the support for custom, mpv-style "user shaders" (.hook),
giving us access to a large variety of pre-existing user shaders
such as RAVU, FSRCNNX, Anime4K, SSimSuperRes, KrigBilateral,
NNEDI3, and more.
In addition to this, major additions include a completely
refactored and fixed AV1 grain generation shader, support for
Vulkan versions higher than 1.0, support for GPU-based timers,
and improved interop APIs for both Vulkan and OpenGL, and new
and improved aspect ratio handling.
Finally, this release also brings with it a major change to the way
HDR and SDR content are mapped between each other, including a new
tone-mapping function based on the industry-standard
ITU-R BT.2390 EETF.
Additions:
  * add pl_swapchain_hdr_metadata, to set HDR metadata on supported
    swapchains (currently only vulkan with VK_EXT_hdr_metadata)
  * add support for vulkan versions higher than 1.0, communicated
    via the new fields api_version and max_api_version
  * add support for GPU-assisted validation and best practices
    layers, via the new field pl_vk_inst_params.debug_extra
  * add helper functions for working with pl_rects, including new
    aspect ratio handling helpers (pl_rect2df_aspect_*)
  * add field pl_vulkan_params.device_uuid to allow choosing the
    vulkan device by its UUID
  * add function pl_vulkan_hold_raw, to hold images without
    actually transitioning its layout and access mode
  * add function pl_vulkan_import, to allow directly re-using an
    existing VkDevice rather than creating a new one; this requires

- Update to version 2.43.1
This release backports a number of bug fixes from master affecting
the v2.43.0 release, and also slightly extends the range of
backwards compatibility with respect to vulkan-headers versions.
(This change is not on master, so this can be seen as a
compatibility release)
Bug fixes:
  * fix GLSL version checks when overriding GLSL versions with
    pl_shader_params.glsl
  * fix minor order-of-operations issue in AV1 grain synthesis
  * fix glInvalidate* backwards compatibility issue
  * fix compilation with older vulkan-headers (e.g. ubuntu 18.04)
  * fix a bug where pl_shader_encode_color sometimes uploaded and
    applied an identity matrix unnecessarily
  * work around upstream issues with MSL shader compilation by
    ensuring all buffer elements are sorted by offset
  * fix hypothetical edge case with swapchain image usages
    forbidden by the swapchain image format
  * fix an issue where blending overlays caused the rest of the
    image to be discarded
Other changes:
  * log the vulkan surface selection choices
  * log the overall library version on initialization
  * add a few more pl_gpu validation checks
  * significantly reduce the CPU consumpation of blocking texture

- Add libepoxy to BuildRequires
- Update to version 2.43.0
The major highlight of this release is the introduction of a new
OpenGL backend, documented in <libplacebo/opengl.h>, which is also
the reason for the major version bump.
Apart from the addition of OpenGL support, this release brings with
it a large number of fixes for backwards compatibility with older
versions of GLSL and GLES, allowing libplacebo to be used to
generate legal shaders for virtually any GLSL version in existence.
Supporting these changes, the test framework has been expanded
considerably to allow for automated testing of older OpenGL context
versions and older GLSL versions.
Additions:
  * add pl_gpu.pci, containing the PCI address of the underlying
    GPU
  * add pl_image.av1_grain, allowing pl_renderer to add AV1 grain
  * add pl_opengl backend (see <libplacebo/opengl.h>)
  * add pl_color_levels_guess, to infer color levels from
    pl_color_repr
  * pl_shader_encode_color now handles non-linear color systems
  * add pl_render_params.force_dither, to force use of the dither
    code
  * add pl_render_params.disable_fbos, to forcibly disable FBOs
  * add pl_vk_inst_params.layers, to allow loading extra vulkan
    layers
  * add a way to restrict the maximum GLSL version provided by the
    various pl_gpu backends, for testing purposes
Changes:
  * load all vulkan function pointers indirectly, using a
    user-provided vkGetInstanceProcAddr function

- Update to version 1.29.1
This is a minor bug fix follow-up, to address one major and two
minor issues with the v1.29.0 release.
Fixes:
  * segfault in the test framework on platforms without vulkan
  * error message spam when rendering to minimized/hidden windows
  * compilation on certain glslang versions

- Update to version 1.29.0
  The key highlights of this release are the change of pl_gpu API
  semantics to use explicit erroring instead of implicit undefined
  behavior, and several important bug fixes related to swapchain
  resizing (in particular, handling of suboptimal swapchains);
  as well as other minor utility changes, bug fixes and performance
  improvements.
  The new pl_gpu API allows clients to duplicate less code related
  to checking parameters and capabilities, as long as they're fine
  with the resulting error messages they might receive. In
  particular, libplacebo no longer aborts on invalid parameters -
  which helped during initial development, but is now suffocating
  clients more than it's helping.
Additions:
  * add a new field pl_fmt.internal_size, which can differ from
    texel_size for emulated formats
  * add 16f / 64f texture formats with host-emulated 32f
    representation
  * expose a pl_vulkan_choose_device helper function
  * add a mechanism for allowing the user to explicitly resize
    suboptimal swapchains rather than having libplacebo take care
    of it
Changes:
  * make pl_gpu log and error gracefully on illegal parameters
    rather than doing undefined behavior (i.e. aborting)
  * creating a host_mapped buffer now requires
    PL_GPU_CAP_MAPPED_BUFFERS
  * drop priv fields from public structs
Fixes and performance improvements:
  * make libplacebo slightly less log spammy in general

- Update to version 1.21.0
  This is a minor / house-keeping release, mostly to get some
  important fixes into distros while also getting support for iGPUs
  requiring non-coherent memory into a "stable" release.
  Additions:
  * shaders.h API users can now override the GLSL version
  * add support for vulkan platforms with non-coherent memory
    (e.g. iGPUs)
  Changes:
  * default GLSL version is now 130 unless otherwise specified
  * signature of pl_shader_alloc now uses a params struct
  * PL_FIX_VER / PL_VERSION are no longer header constants
  * the renderer will now automatically adjust deband grain scale
    for HDR
  Fixes and performance improvements:
  * on GLSL < 130, shaders now correctly use texture2D etc.
  * fix a bug where async transfer was never actually used, due to
    incorrect alignment checks
  * fixed some issues that could lead to symbol conflicts
  * don't require large vertex buffers be host-visible
    (usually impossible)
  * correctly detect swapchain image feature flags
  * turned a few 1ms busy loops into infinite waits
  * fix compilation on some platforms that require SPIRV-Tools
  * fix vkCreateEvent error spam on MoltenVK
  * bump queued command limit from 64 to 1024

- Build with (preferred) shaderc now that it’s packaged in TW
- Update to version 1.18.0
  The major changes of this release include a new and completely
  overhauled HDR tone mapping algorithm, support for importing
  backing memory for textures and buffers (such as via dmabuf fds),
  as well as a swapchain resizing API that, among other benefits,
  allows libplacebo to function properly on Wayland.
  There is also now support for generating CPU-backed "dummy
  resources" for things like lookup tables or convolution kernels,
  for users who prefer managing their own GPU resources.
  This allows pl_shader-level API users to access the full host of
  libplacebo shaders without being restricted the lack of a pl_gpu.
  Additions:
  * pl_color_space now has a sig_scale field, which allows
    modifying the signal range without affecting the transfer
    function's shape. (Effectively, by "stretching" it).
    This can be useful when dealing with HDR material encoded in a
    non-HDR curve such as linear light.
  * Add support for importing handles (including pl_sync objects
    and pl_shared_mem). Currently, only memory can be imported.
  * Add partial support for dmabuf fd interop. Currently does not
    support dma layout modifiers, so the usefulness of this feature
    is limited.
  * Allow importing external memory when creating textures.
  * Add a way to overexpose HDR material to bring its brightness up
    to more easily viewable levels.
  * Add pl_var_int to go alongside the other gpu.h helpers.
  * Add a way to create CPU-backed "dummy" instances of pl_gpu.
    These are not capable of compiling or executing any shaders,
    so they're only useful for users who want to generate and

    and imported into other foreign APIs such as CUDA.
  * The buf_offset parameter to pl_tex_transfer no longer needs to
    be strictly aligned to a multiple of 4. The minimum alignment
    is now 1, however users are strongly recommended to stick to
    the multiple-of-4 alignment (or ideally align_tex_xfer_offset)
    for performance reasons.
  * The chromatic adaptation method in pl_get_color_mapping_matrix
    has been adjusted. We now use an LMS model derived from
    CIECAM97's revised linear Bradford matrix, rather than the
    non-linear matrix that was being used previously (incorrectly
    so, due to the lack of the required nonlinearity).
  * The order of fields in pl_rect3d has been changed for
    consistency with the other rect types.
  * Fix an alignment issue that could happen sometimes with
    pl_buf_write for odd write sizes.
  * Fix an alignment bug when uploading partial textures when async
    transfer is enabled on some devices.
  * Fix crash in pl_color_primaries_is_wide_gamut on DISPLAY_P3.
  * Fix an error when re-using shader objects between polar and
    non-polar samplers. This is now safe to do.
