/*
* Tries to sanitize the dmabuf to conform to the values expected
* by Vulkan/EGL which should also be the values expected by
* Wayland compositors
*
* We put these sanitized values into the GdkDmabufTexture, by
* sanitizing the input from GdkDmabufTextureBuilder, which are
* controlled by the callers.
*
* Things we do here:
*
* 1. Disallow any dmabuf format that we do not know.
*
* 2. Ignore non-linear modifiers.
*
* 3. Try and fix various inconsistencies between V4L and Mesa
* for linear modifiers, like the e.g. single-plane NV12.
*
* *** WARNING ***
*
* This function is not absolutely perfect, you do not have a
* perfect dmabuf afterwards.
*
* In particular, it doesn't check sizes.
*
* *** WARNING ***
