2020-05-19render/egl: introduce wlr_egl_unset_currentSimon Ser
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. Closes: https://github.com/swaywm/wlroots/issues/2197
2020-04-28render/texture: add width and height fieldsSimon Ser
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.
2020-04-22render/gles2: add wlr_gles2_renderer_check_extSimon Ser
2020-04-09render: only expose linux-dmabuf if EGL extension is supportedSimon Ser
Only expose linux-dmabuf extension if EGL_EXT_image_dmabuf_import_ext is supported. Closes: https://github.com/swaywm/wlroots/issues/2076
2020-04-09render/gles2: only call wlr_egl_bind_display if supportedSimon Ser
This allows us to hard-fail if the extension is advertised but we fail to enable it.
2020-03-23Return failure of wlr_renderer_init_wl_display()Isaac Freund
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.
2020-03-09render/gles2: remove duplicated format listSimon Ser
2020-01-13render/gles2: unbind textures after useSimon Ser
Keeping textures bound results in hard-to-debug situations where some GL operations incorrectly affect the texture.
2019-12-20Refactor EGL/GL API loadingSimon Ser
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
2019-11-26render/gles2: do not set GL_TEXTURE_MAG_FILTERRonan Pigott
2019-11-20Add -Wmissing-prototypesSimon Ser
This requires functions without a prototype definition to be static. This allows to detect dead code, export less symbols and put shared functions in headers.

2019-11-07render/gles2: provide public API to access GL textureSimon Ser
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].

2019-11-06render/gles: Simplify textures a bitScott Anderson
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.
2019-10-16render/gles2: don't unset the current EGL surface when destroying textureSimon Ser
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.

2018-11-04render/gles2: remove assumptions about supported formatsemersion
We were assuming GL_BGRA_EXT was always supported. We now check that it's supported for rendering. We fail if it isn't because this format is specified as "always supported" by the Wayland protocol. We also check if it's supported for reading pixels. A new preferred_read_format function returns the preferred format that can be used to read pixels. This is used by the screencopy protocol.

Also rephrase the write_pixels comment.
2018-10-15Remove fmt parameter from wlr_texture_write_pixelsnyorain
It's not allowed to change the format of a texture so remove the confusing parameter.

Texture functions, that create and manipulate textures should switch the current context if necessary. thanks to: @emersion Fixes #934

It's possible to implement it outside the renderer, by creating a texture and destroying it right away. This reduces the API surface of the renderer.
