- Update to 0.5.0
  This release brings with it greatly improved support for HDR (including
  HDR-in-SDR emulation, native HDR passthrough and improvements to the
  HDR->SDR tone mapping algorithm), as well as support for ICC profiles
  and external VkImage interop (needed for e.g. hardware decoding).

Additions:
  * Add support for treating an SDR curve as an HDR curve by
    overriding/providing the true target peak. This essentially allows you
    to calibrate a true HDR device to a typical SDR curve and use it to
    display HDR media, at the cost of bit precision
  * Add more values to enum pl_chroma_location
  * Add a scale factor to struct pl_sample_src, which is useful for e.g.
    debanding on bit-shifted inputs
  * Add a new function to infer/guess unknown pl_color_space fields
  * Add support for 3DLUTs / ICC profiles (via LittleCMS), including
    support for assigning ICC profiles to the `pl_render_image` and
    `pl_render_target` structs
  * Allow enabling optional extra vulkan device/instance extensions, as
    well as listing what extensions were actually loaded
  * Add an API for VkImage interop with user code, e.g. to wrap mapped
    hardware decoding planes into `pl_tex`, plus all synchronization code
    and extra metadata necessary to make this interop safe
  * Implement support for native HDR output on supported platforms

Changes:
  * Separate the texture from the plane data struct in `pl_upload_plane`
  * Swapchain FBOs are now guaranteed to be blittable (e.g. pl_tex_clear)
  * Tone mapping is no longer done for desaturation steps. Users wanting
    high quality desaturation should use ICC profiles
  * Change the types of various fields in struct pl_gpu_limits
  * Slightly relax the sizing requirements of pl_tex_transfer
  * Change the default value for pl_tex_transfer_params.stride_w/h.
    Instead of defaulting to the image size, they now default to the rect to
    be transferred
  * Texture transfer buffer offsets must (now) be aligned to the texel
    size, in addition to being a multiple of 4
  * Change the API of `pl_color_space_equal` to be consistent with the
    rest of the colorspace APIs
  * Allow the `pl_upload_plane` helpers to upload from buffers as well
  * Switch the type of mapped buffer pointers from char* to uint8_t*
  * Rename DCI_P3 to Display_P3, and add DCI_P3 (using the actual DCI white
    point)

Fixes and performance improvements:
  * Fix some compatibility issues with GLSL 120
  * Prevent desaturation from exploding when tone mapping to HDR, or when
    tone mapping a very bright HDR scene to SDR
  * Implement the fully parametrized BT.2100 (HLG) OOTF in both
    directions, based on the tagged/inferred signal peak
  * Fix an issue preventing the out-of-gamut feature from working
    correctly on HDR displays
  * Fix a segfault that occurs when instance creation fails
  * Fix an issue where `peak_detect_frames` was sometimes too low
  * Allow debanding to take care of implicit bilinear sampling in cases
    where no other scaler is requested, thus avoiding an unnecessary FBO
    indirection
  * Only run the debanding algorithm on the parts of the image we will
    actually be displaying. This is relevant when cropping
  * Fix an issue where PL_TONE_MAPPINg_MOBIUS could fail in certain
    (unrealistic) scenarios involving HDR-in-SDR emulation
  * Fix an issue where vulkan could sometimes modify commands after
    submitting them, when recreating vertex buffers
  * Make an effort to reuse the same vertex buffer when the contents don't
    change from the previous invocation
  * Fix the glslang locale work-arounds on windows
  * Fix an issue where trying to upload from a too-large texel buffer
    results in an assertion failure rather than a clean error
  * Fix an issue where the usage of VkEvents prevented libplacebo from
    working on platforms where they were unsupported (e.g. MoltenVK)
  * Support and use vulkan push descriptors where supported. This avoids
    having to maintain, update and synchronize descriptor sets
  * Correctly disable signal linearization on low-bit depth FBOs
  * Prevent a crash on the (pathological) case of a shader with no
    descriptors
  * Fix a bug in the size limit calculations for 2D/3D LUTs
  * Use optimization level "performance" instead of "size" for shader
    compilation
  * Fix an abort() when trying to render to a non-storable FBO when using
    a final pass that requires compute shaders (e.g. HDR peak detection)
