Rename wlr_renderer_get_dmabuf_formats to
wlr_renderer_get_dmabuf_texture_formats. This makes it clear the formats
are only suitable for creating wlr_textures.
On some setups (e.g. remote access via SSH) the current user won't have
the permission to open the primary node at all. It's still possible to
use drmGetDevices to match the primary node name returned by EGL.

The swapchain maximum capacity is set to 4, so that we have enough room
for:
- A buffer currently displayed on screen
- A buffer queued for display (e.g. to KMS)
- A pending buffer that'll be queued next commit
- An additional pending buffer in case we want to invalidate the
currently pending one
Don't force compositors to check when an empty shape is being renderered.
References #2282. This was motivated by dwl crashing when setting window
borders to 0 (djpohly/dwl#51).
texcoord is a vector of coordinates, with the first member being the X
axis value and the second member being the Y axis value. It makes more
sense to use the accessors with the same names.
Prior to this commit, wlr_egl_init seemed to assume the extension string
queried via EGL_NO_DISPLAY was a subset of the extension string queried
via an initialized display. This isn't correct.
EGL_EXT_client_extensions [1] defines two types of extensions: client
extensions and display extensions. The set of supported client and
display extensions are disjoint (ie. an extension is either a client or
a display extension, not both). Client extensions are queried via
EGL_NO_DISPLAY, display extensions are queried via an initialized
display.
Rename the variables to make this clear. Remove the misleading comment.
Log both client and display extensions.

This leaves an EGL context current behind. wlr_gles2_renderer_create was
assuming the EGL context was already current because of this (because it
called a GL function right off the bat).
After swapping buffers, it doesn't make sense to perform more rendering
operations. Unset the context to reflect this.
This commit makes it so the context is always only current between
wlr_egl_make_current and wlr_egl_swap_buffers.
This is an alternative to [1].

This function can be called after wlr_egl_make_current to cleanup the
EGL context. This avoids having lingering EGL contexts that make things
work by chance.

Instead of requiring compositors to call wlr_texture_get_size each time
they want to access the texture's size, expose this information as
wlr_texture fields.
This makes it easier for the user of this library to properly handle
failure of this function.
The signature of wlr_renderer_impl.init_wl_display was also modified to
allow for proper error propagation.
Add a wlr_renderer.rendering bool, set it to true between
wlr_renderer_begin() and wlr_renderer_end(). Assert we're rendering when
calling functions that render.
