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
assuming the EGL context was already current because of this (because it
called a GL function right off the bat).

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.

Isaac Freund c682d97841 Return failure of wlr_renderer_init_wl_display()
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.

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.

render/gles2: remove assumptions about supported formats
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.

Redesign wlr_texture
- Textures are now immutable (apart from those created from raw

- 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.

- remove trivial destroy() function
 - make sure we check impl and impl->destroy before calling
 - always call free if not implemented

Tony Crisci 9119be1dd1 Remove unnecessary calls to glActiveTexture
Since wlroots shaders only use one texture at a time (ie there is only one
sampler2D variable in any shader), it is unnecessary to switch between active
texture units at this time.

Tony Crisci effea557bb Implement destroying surfaces
Add a signal for wlr_surface destruction on the wlr_surface that compositors
can listen to to remove the surface from their state.

Implement a listener for this in the example wl_compositor to remove the
surface from its internal list of surfaces.

Destroy the surface in the compositor destroy_surface callback given when the
surface resource was created.

Add a reference to the surface resource to the wlr_surface so a compositor can
find it in its list of resources upon wlr_resource destruction.

Tony Crisci 6610aa7ca7 Implement shm buffer surface attach interface
Implement surface_attach method. This is called when a client attaches an shm
buffer with wl_surface_attach().

Implement the GLES2 interface for attaching shm buffers. This creates an opengl
texture with the shm buffer contents for the surface.

This commit also includes some working code to render the surfaces onto the
screen for demonstration purposes.
