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 afdf4dc890 render/gles2: make EGL context current in bind_buffer
Instead of requiring callers to manually make the EGL context current
before binding a buffer and unsetting it after unbinding a buffer, do
it inside wlr_renderer_bind_buffer.

This hides renderer-specific implementation details inside the
wlr_renderer interface. Non-GLES2 renderers may not use EGL.
This removes all EGL dependencies from the backends.

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.

render/gles2: save/restore EGL context in destroy_buffer
It can be surprising that destroying a buffer changes the EGL context,
especially since this can be triggered from anywhere wlr_buffer_unlock
is called.

Prevent this from happening by saving and restoring the EGL context.

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 e91417ea8d render: stop making EGL context current in wlr_egl_init
This leaves an EGL context current behind. wlr_gles2_renderer_create was

- 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.
