Simon Ser d6e250b389 render/egl: fix swapping with no damage
According to the spec:

> If <n_rects> is 0 then <rects> is ignored and the entire
> surface is implicitly damaged and the behaviour is equivalent
> to calling eglSwapBuffers.

When we want to swap with an empty damage region, set the damage to a single
empty rectangle.

Alyssa Ross 95b22619e0 Fix missing headers when building without X11
The deleted includes are redundant, because other headers will include
the necessary files. Additionally, they cause build failures, because
including EGL/egl.h or EGL/eglext.h directly, instead of through
wlr/render/egl.h or wlr/render/interface.h, will mean that
MESA_EGL_NO_X11_HEADERS will not have been defined, and so the EGL
headers will attempt to pull in unnecessary X11 headers that may not
exist on the system.

For the headers produced by glgen.sh, the includes couldn't simply be
deleted, because no other header would include the EGL headers. Neither
wlr/render/egl.h or wlr/render/interface.h felt appropriate to include,
so I opted instead to copy the MESA_EGL_NO_X11_HEADERS definition before
the EGL includes.

render: introduce wlr_drm_format_set
This types adds a container for formats + modifiers.

A list that is of [format [modifier]] was chosen instead of
[format modifer] because that is how GBM accepts them.

Ilia Bozhinov fb5691b6cc output: add wlr_output_preferred_read_format()
The read format is dependent on the output, so we first need to make it
current. This fixes a race condition in wlr-screencopy-v1 where a dmabuf
client would cause EGL_NO_SURFACE to be bound at the time when
screencopy needs to query for the preferred format, causing GL errors.

render/gles2: remove assumptions about supported formats
We were assuming GL_BGRA_EXT was always supported.

We now check that it's supported for rendering. We fail if it isn't because
this format is specified as "always supported" by the Wayland protocol.

We also check if it's supported for reading pixels. A new preferred_read_format
function returns the preferred format that can be used to read pixels. This is
used by the screencopy protocol.

Fix include path for (libdrm/)drm_fourcc.h
This PR broke a private nixpkgs definition I have for wlroots: https://github.com/swaywm/wlroots/pull/1304

It is fixed by changing `#include <drm_fourcc.h>` to `#include <libdrm/drm_fourcc.h>`, which follows what is already done in the dmabuf example.

nyorain affbfb6a28 Support older wlr_linux_dmabuf_v1 clients
If a client uses an older version of the dmabuf protocol, use the
`formats` event instead of `modifiers` (since that didn't exist in older
versions).
With a bit of necessary guessing, support dmabuf importing even when
EGL_EXT_image_dma_buf_import_modifiers isn't present instead of
failing up front.

Ilia Bozhinov 24cf70ae96 backends: implement custom EGL and renderer initialization
Compositors now have more control over how the backend creates its
renderer. Currently all backends create an EGL/GLES2 renderer, so
the necessary attributes for creating the context are passed to a
user-provided callback function. It is responsible for initializing
provided wlr_egl and to return a renderer. On fail, return 0.
