2021-06-30render/egl: replace wlr_egl_create with wlr_egl_create_with_drm_fdSimon Ser
We never create an EGL context with the platform set to something other than EGL_PLATFORM_GBM_KHR. Let's simplify wlr_egl_create by taking a DRM FD instead of a (platform, remote_display) tuple. This hides the internal details of creating an EGL context for a specific device. This will allow us to transparently use the device platform [1] when the time comes. [1]: https://github.com/swaywm/wlroots/pull/2671
2021-06-24render/egl: make most functions privateSimon Ser
The wlr_egl functions are mostly used internally by the GLES2 renderer. Let's reduce our API surface a bit by hiding them. If there are good use-cases for one of these, we can always make them public again. The functions mutating the current EGL context are not made private because e.g. Wayfire uses them.
2021-06-09render: drop wlr_ prefix from wlr_renderer_bind_bufferSimon Ser
Make it clear this function is a private wlroots API and will stay that way.
2021-06-07render/pixman: implement texture_from_bufferSimon Ser
2021-05-31render/allocator: add wlr_allocator.buffer_capsSimon Ser
This allows users to know the capabilities of the buffers that will be allocated. The buffer capability is important to know when negotiating buffer formats.
2021-05-30render/gles2: fix texture cleanup on destroySimon Ser
When importing a DMA-BUF wlr_buffer as a wlr_texture, the GLES2 renderer caches the result, in case the buffer is used for texturing again in the future. When the wlr_texture is destroyed by the caller, the wlr_buffer is unref'ed, but the wlr_gles2_texture is kept around. This is fine because wlr_gles2_texture listens for wlr_buffer's destroy event to avoid any use-after-free. However, with this logic wlr_texture_destroy doesn't "really" destroy the wlr_gles2_texture. It just decrements the wlr_buffer ref'count. Each wlr_texture_destroy call must have a matching prior wlr_texture_create_from_buffer call or the ref'counting will go south. Wehn destroying the renderer, we don't want to decrement any wlr_buffer ref'count. Instead, we want to go through any cached wlr_gles2_texture and destroy our GL state. So instead of calling wlr_texture_destroy, we need to call our internal gles2_texture_destroy function. Closes: https://github.com/swaywm/wlroots/issues/2941
2021-05-17render/gles2: implement texture_from_bufferSimon Ser
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.
2021-05-17render: introduce wlr_texture_from_bufferSimon Ser
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.
2021-05-05render: add DRM dumb buffer allocatorSimon Zeni
2021-05-05render/gbm_allocator: duplicate drm fd during creation processSimon Zeni
2021-04-29render/allocator: add allocator_autocreate_with_drm_fdSimon Ser
Same as wlr_allocator_autocreate, but allows the caller to force a DRM FD. Similar to renderer_autocreate_with_drm_fd.
2021-04-29render: remove wlr_ prefix from wlr_renderer_autocreate_with_drm_fdSimon Ser
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.

2021-04-17render: introduce shared memory allocatorSimon Ser
It allocates in local main memory via shm_open, and provides a FD to allow sharing with other processes. This is suitable for software rendering under the Wayland and X11 backends.

2021-04-08render: drop support for ellipsesSimon Ser
For anything more complicated than quads, compositors can easily ship their own shaders. Closes: https://github.com/swaywm/wlroots/issues/2759

2021-03-10output: improve transform matrix calculationSimon Zeni
Compute only the transform matrix in the output. The projection matrix will be calculated inside the gles2 renderer when we start rendering. The goal is to help the pixman rendering process.

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
