  Message : Vulkan: Reduce pre-rotation spec const to bool The specialization constant now only dictates whether x and y should be swapped. The complete 8 possible states of rotation and y-flip are achieved by using this swap in combination with a driver uniform for x and y flip. Swapping is still a specialization constant to avoid degrading performance of dFdx/dFdy which otherwise would need both to be evaluated instead of one. On platforms which don't support pre-rotation, the specialization constant will never change and driver uniforms entirely govern y-flip. On platforms that do support pre-rotation, only two variations of the pipeline are needed.

• ANGLE back-ends

  This folder contains shared back-end-specific implementation files. The classes and types in renderer are not specified by GLES. They instead are common to all the various ANGLE implementations.

  See renderer_utils.h for various cross back-end utilties.

  ANGLE Formats

  The ANGLE format class, angle::Format, works as a union between GLES and all the various back-end formats. It can represent any type of format in ANGLE. e.g. Formats in Vulkan that don't exist in GLES, or DXGI formats that don't exist in GLES, or Windows/Android surface configs that don't exist anywhere else.

  The glInternalFormat member of angle::Format represents the "closest" GL format for an ANGLE format. For formats that don't exist in GLES this will not be exactly what the format represents.

  The back-ends also define their own format tables. See the Vulkan Format table docs and the [D3D11 format table docs][D23D11FormatDocs].

  DXGI Format Info

  DXGI formats are used in both the GL and D3D11 back-end. Therefore the generated info table lives in this common shared location.

  The DXGI info table is generated by gen_dxgi_format_table.py and sources data from dxgi_format_data.json. The main purpose of the table is to convert from a DXGI format to an ANGLE format, where the ANGLE format should have all the necessary information.
