- 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
