[Mesa-dev] [PATCH v2 00/14] implement EGL_EXT_image_dma_buf_import_modifiers v2

[Varad Gautam]

This is the second revision to the EGL_EXT_image_dma_buf_import_modifiers [1]
series at [2], addressing the comments received. This diverges from v1 due to
some reordered/squashed changes, hence the resend.

Major modifications include:
* Both format and modifier queries are now handled in the driver, instead of
advertising all formats as supported by all drivers, and exposed under a
common PIPE_CAP_QUERY_DMABUF_ATTRIBS flag.
* The implementation makes sure that the same modifier is passed for all planes
used for EGLImage creation.
