Simon Ser f73c04b801 render/pixman: avoid sqrt() in render_quad without rotation
When the matrix doesn't have a rotation, we can avoid a sqrt() call.

Tested with Sway's tabbed containers.

Simon Ser 66e100ffbf render/gbm_allocator: add support for gbm_bo_get_fd_for_plane
See [1]. This allows us to remove the workaround for GBM API
limitations.

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
This adds a a function to create a wlr_texture from a wlr_buffer.

The main motivation for this is to allow the renderer to create a
single wlr_texture per wlr_buffer. This can avoid needless imports
by re-using existing textures.

Simon Ser 9221ed7b4c render/gles2: add gles2_texture_create
This centralizes the wlr_texture initialization.

In future commits, more fields will need to get initialized.

Simon Ser 101b9a193d render/egl: query and display EGL driver name
GL_RENDERER typically displays a human-readable string for the name
of the GPU, and EGL_VENDOR typically displays a human-readable string
for the GPU manufacturer. EGL_DRIVER_NAME_EXT should give the name of
the driver in use.

Rendering a wlr_texture with a different wlr_renderer is invalid.
Add an assert to make sure this doesn't happen.

Simon Ser 5be76bb047 render/allocator: add allocator_autocreate_with_drm_fd
Same as wlr_allocator_autocreate, but allows the caller to force a
DRM FD.

Similar to renderer_autocreate_with_drm_fd.

Simon Ser 619a975025 render: remove wlr_ prefix from wlr_renderer_autocreate_with_drm_fd
This function is only required because the DRM backend still needs
to perform multi-GPU magic under-the-hood. Remove the wlr_ prefix
to make it clear it's not a candidate for being made public.

Simon Ser 24fde77c62 buffer: add format param to get_data_ptr
Allow wlr_buffer_impl.get_data_ptr to return a format.

This allows the Pixman renderer to not care about get_dmabuf/get_shm,
and only care about get_data_ptr. This will also help with [1], because
client wl_shm buffers can't implement get_shm.

Simon Ser af78ecb86b render: unconditionally read WLR_RENDERER
Prior to this commit, WLR_RENDERER was only looked up when the
backend returned a DRM FD.

Make it so WLR_RENDERER is always looked up, so that running wlroots
on a system without a GPU and with WLR_RENDERER=gles2 fails as
expected instead of falling back to the Pixman renderer.

by one until one is created successfuly.

Simon Ser c6b009ef85 render: introduce shared memory allocator
It allocates in local main memory via shm_open, and provides a FD

Simon Ser 004cf887b7 render/gles2: prevent imported DMA-BUF textures from being mutated
The compositor shouldn't write to client buffers if the client
attaches a DMA-BUF to a wl_surface, then attaches a shm buffer.
Make gles2_texture_write_pixels return an error to prevent this
from happening.

Roman Gilg b36af22c94 backend: move get_drm_fd to public interface

make use of it.

This is unused in wlroots, and the use-cases for compositors are

Simon Ser b514d4afe2 render/egl: stop relying on platform for high priority
All backends use the GBM platform. We can't use it to figure out
whether the DRM backend is used anymore.

Let's just try to always request a high-priority EGL context. Failing
to do so is not fatal.

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.
