Simon Ser 9ecfa4343a render: remove wlr_texture_to_dmabuf
This is unused in wlroots, and the use-cases for compositors are
pretty niche since they can access the original DMA-BUF via the
wlr_buffer.

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);

Simon Ser 642b349e94 render/gles2: restore EGL context after texture operations
It can be surprising and unexpected that texture operations (such as
texture upload and import) change the current EGL context, especially
when it's done under-the-hood by wlroots in response to wl_surface
requests.

To prevent surprises, save and restore the previous EGL context.

Simon Ser 1dbcfdaf81 render/gles2: remove gles2_procs
Move the global into wlr_gles2_renderer. This removes global state and
allows us to have multiple renderers with different GL loaders.

Simon Ser 26af316b3b render/gles2: make wlr_gles2_texture_from_* private
These functions are unused by compositors (see e.g. [1]) and prevent
wlr_gles2_texture from accessing wlr_gles2_renderer state. This is an
issue for proper teardown [2] and for accessing GLES2 extensions.

Simon Ser a3ba82885c render: choose DMA-BUF texture target via eglQueryDmaBufModifiersEXT
EGL_EXT_image_dma_buf_import_modifiers tells us whether we should use
GL_TEXTURE_2D or GL_TEXTURE_EXTERNAL_OES. Using the right texture target
can fix some failures and/or improve performance on some drivers.

This does the same as a Weston commit [1].

Simon Ser 1edc42157b render/egl: introduce wlr_egl_unset_current
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.

Simon Ser 06f4c3945d render/texture: add width and height fields
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.

Simon Ser 515679e4fe Refactor EGL/GL API loading
Remove glapi.sh code generation, replace it with hand-written loading
code that checks extension strings before calling eglGetProcAddress.

The GLES2 renderer still uses global state because of:

- {PUSH,POP}_GLES2_DEBUG macros
- wlr_gles2_texture_from_* taking a wlr_egl instead of the renderer

Simon Ser 447835afc1 render/gles2: provide public API to access GL texture
Prior to this commit, compositors needed to render the texture to an
intermediate off-screen buffer using wlr_renderer APIs if they wanted to
use a custom rendering path (e.g. render to a 3D scene).

A new wlr_gles2_texture_get_attribs exposes the GL texture target and ID
so that compositors can render wlr_textures with their own shaders. An
example of a compositor doing so is available at [1].

Scott Anderson 85a2ee6d30 render/gles: Simplify textures a bit
We don't need our own enum for types. Instead we just use
GL_TEXTURE_{2D,EXTERNAL_OES}, which already describes usage.

Also fixes a situation where we were using GL_TEXTURE_2D in a situation
we should not have. wl_drm buffers are always GL_TEXTURE_EXTERNAL_OES,
no matter if they're RGB or any other format.

Simon Ser 6bb7639a0f render/gles2: don't unset the current EGL surface when destroying texture
When a texture is destroyed between wlr_egl_make_current and
wlr_egl_swap_buffers, it resets the current EGL surface to NULL. This
makes wlr_egl_swap_buffers fail.

If the EGL context is already current, there's no need to reset it.

Redesign wlr_texture
- Textures are now immutable (apart from those created from raw
  pixels), no more invalid textures
- Move all wl_drm stuff in wlr_renderer
- Most of wlr_texture fields are now private
- Remove some duplicated DMA-BUF code in the DRM backend
- Add more assertions
- Stride is now always given as bytes rather than pixels
- Drop wl_shm functions

Fun fact: this patch has been written 10,000 meters up in the air.
