v0.2.0

Additions:
- Add a public "renderer" API. This is currently very WIP, and not ready
  for stable usage yet. Both the API and the implementation are in flux,
  but the general goal is to make it easier to use libplcaebo to just
  render some data in the optimal way.
- Add pl_deband_default_params
- Expand shader system to support shader merging. This is not directly
  publicly useful yet, but it's used internally in the renderer.
- Allow dispatching to sub-rects of the render target
- Expand the scaling API to allow disabling antialiasing
- Add high quality dithering algorithms (blue noise, arbitrary size bayer
  matrix). This uses a new, genearlized shader LUT mechanism which
  allows the LUT to manifest itself either as a texture, a uniform
  float[] or as an in-line constant array depending on
  environment/hardware capabilities. As such, this can be used to enable
  dithering even without the use of a RA.

Changes:
- Minor RA API changes here and there (e.g. signed -> unsigned stride)

Fixes:
- Improved check logic for various shaders
- More descriptive variable names in some of the generated shaders
- Fix overflow when dithering to bit depths greater than 32
- Fix the RA format finding logic in some cases
- Make the scalers correctly support flipped scaling rects
- Fix some incorrect vulkan texture barriers
- Fix some locale issues on BSD
- GLSL 120 compat fix with the dithering algorithm
- Fix vulkan command polling logic to avoid blocking for longer than
  intended

v0.1.2

Fixes:
- Add missing header file
- Cosmetic fixes in the generated shaders

Improvements:
- Log slightly more debugging information for RAs
- Slight improvement of the internal PRNG
- Add travis CI support

Release v0.1.1

This is a minor bug fix release, to solve some issues that arose while
integrating libplacebo into VLC 3.0.

Fixes:
- various fixes under NDEBUG
- removed the LIBPLACEBO_ENABLE_SECURITY_BUGS nag under NDEBUG
- removed the LIBPLACEBO_LEAK_REPORT check under NDEBUG

Release v0.1.0

This represents the initial release, mostly so we can get VLC with basic
libplacebo support out of the way.

As of v0.1, libplacebo only supports vulkan, and only exposes the
low-level interfaces (dispatch, shader, ra). So as of now, libplacebo is
only useful either as a GLSL shader generator (shaders.h), or as an
offline tool for processing images (dispatch.h + vulkan). There is
currently no high-level image/video rendering interface, and no support
for OpenGL whatsoever.

OpenGL support is planned for v0.2, and the addition of a high level
renderer is planend for v0.3.
