Simon Ser 2fa47c1837 render: drop wlr_renderer_impl.init_wl_display
Now that we have our own wl_drm implementation, there's no reason
to provide custom renderer hooks to init a wl_display in the
interface. We can just initialize the wl_display generically,
depending on the renderer capabilities.

Simon Ser e5b5592a95 render: remove wl_drm support from wlr_renderer
Everything needs to go through the unified wlr_buffer interface
now.

If necessary, there are two ways support for
EGL_WL_bind_wayland_display could be restored by compositors:

- Either by using GBM to convert back EGL Wayland buffers to
  DMA-BUFs, then wrap the DMA-BUF into a wlr_buffer.
- Or by wrapping the EGL Wayland buffer into a special wlr_buffer
  that doesn't implement any wlr_buffer_impl hook, and special-case
  that buffer type in the renderer.

Simon Ser 1db976cecb render/egl: replace wlr_egl_create with wlr_egl_create_with_drm_fd
We never create an EGL context with the platform set to something
other than EGL_PLATFORM_GBM_KHR. Let's simplify wlr_egl_create by
taking a DRM FD instead of a (platform, remote_display) tuple.

This hides the internal details of creating an EGL context for a
specific device. This will allow us to transparently use the device
platform [1] when the time comes.

Simon Ser a2419eb4ea render/egl: make most functions private
The wlr_egl functions are mostly used internally by the GLES2
renderer. Let's reduce our API surface a bit by hiding them. If
there are good use-cases for one of these, we can always make them
public again.

The functions mutating the current EGL context are not made private
because e.g. Wayfire uses them.

Simon Ser 2806154900 render: add missing arg to wlr_renderer_impl.get_buffer_caps
The types of buffers supported by the renderer might depend on the

DMA-BUFs if the necessary EGL extensions are available.

Pass the wlr_renderer to get_buffer_caps so that the renderer can
perform such checks.

Simon Ser abf527b075 render/gles2: fix texture cleanup on destroy
When importing a DMA-BUF wlr_buffer as a wlr_texture, the GLES2
renderer caches the result, in case the buffer is used for texturing
again in the future. When the wlr_texture is destroyed by the caller,
the wlr_buffer is unref'ed, but the wlr_gles2_texture is kept around.
This is fine because wlr_gles2_texture listens for wlr_buffer's destroy
event to avoid any use-after-free.

However, with this logic wlr_texture_destroy doesn't "really" destroy
the wlr_gles2_texture. It just decrements the wlr_buffer ref'count.
Each wlr_texture_destroy call must have a matching prior
wlr_texture_create_from_buffer call or the ref'counting will go south.

Wehn destroying the renderer, we don't want to decrement any wlr_buffer
ref'count. Instead, we want to go through any cached wlr_gles2_texture
and destroy our GL state. So instead of calling wlr_texture_destroy, we
need to call our internal gles2_texture_destroy function.

Simon Ser f6ba26ff58 render/gles2: implement texture_from_buffer
Make it so wlr_gles2_texture is ref'counted (via wlr_buffer). This
is similar to wlr_gles2_buffer or wlr_drm_fb work.

When creating a wlr_texture from a wlr_buffer, first check if we
already have a texture for the buffer. If so, increase the
wlr_buffer ref'count and make sure any changes made by an external
process are made visible (by invalidating the texture).

When destroying a wlr_texture created from a wlr_buffer, decrease
the ref'count, but keep the wlr_texture around in case the caller
uses it again. When the wlr_buffer is destroyed, cleanup the
wlr_texture.

Simon Ser 9d55f712e3 render: introduce wlr_texture_from_buffer

by re-using existing textures.

Simon Ser b89bcffea4 render/egl, backend/wayland: add workaround for split render/display setups
Split render/display setups have two separate devices: one display-only
with a primary node, and one render-only with a render node. However
in these cases the EGL implementation and the Wayland compositor will
advertise the display device instead of the render device [1]. The EGL
implementation will magically open the render device when the display
device is passed in.

So just pass the display device as if it were a render device. Maybe in
the future Mesa will advertise the render device instead and we'll be
able to remove this workaround.

Simon Ser bfd020047d render/gles2: remove current_buffer checks
All backends now use wlr_swapchain. This means the renderer is
guaranteed to have a current_buffer bound.

Remove the legacy code used for EGLSurface.

Simon Ser 6ca59519c9 render/gles2: check buffer stride when uploading texture
If the stride is too small, the driver could end up segfaulting
(e.g. radeonsi segfaults in __memmove_sse2_unaligned_erms).

render/gles2: remove YUV blocklist
Mesa provides YUV shaders, and can import multi-planar YUV DMA-BUFs
as a single EGLImage. Remove the arbitrary limitation.

If the driver doesn't support importing YUV as a single EGLImage,
the import will fail and the result will be the same anyways.

Quantum 975d14b799 render/wlr_texture: clamp texture coordinates to edge by default
Clamping texture coordinates prevents OpenGL from blending the left and
right edge (or top and bottom edge) when scaling textures with GL_LINEAR
filtering. This prevents visual artifacts like swaywm/sway#5809.

Per discussion on IRC, this behaviour is made default. Compositors that want
the wrapping behaviour (e.g. for tiled patterns) can override this by doing:

    struct wlr_gles2_texture_attribs attribs;
    wlr_gles2_texture_get_attribs(texture, &attribs);

    glBindTexture(attribs.target, attribs.tex);
    glTexParameteri(attribs.target, GL_TEXTURE_WRAP_S, GL_REPEAT);
    glTexParameteri(attribs.target, GL_TEXTURE_WRAP_T, GL_REPEAT);
    glBindTexture(attribs.target, 0);

Brandon Dowdy f1d37c54c8 render/egl: add check for EGL_KHR_surfaceless_context
As surfaces are no longer going to be used for wlr_egl, I may as well just go and add this check as it is needed for safety whenever surface-less rendering is being used.

Brandon Dowdy 8aa38fe73e render/egl: remove *config_attribs and wlr_egl->config
Breaking changes:

Both "EGLint *config_attribs" and "wlr_egl->config" no longer exist.
