When creating an EGLImage from a struct wl_buffer * this ensures
that we create an XRGB8888 image if the wayland buffer doesn't have an
alpha channel. To determine if a wl_buffer has a valid alpha channel
this patch adds an internal wayland_drm_buffer_has_alpha() function.
It's important to get the internal format for an EGLImage right so that
if a GL texture is later created from the image then the GL driver will
know if it should sample the alpha from the texture or flatten it to
a constant of 1.0.
This avoids needing fragment program workarounds in wayland compositors
to manually ignore the alpha component of textures created from wayland
buffers.
krh: Edited to use wl_buffer_get_format() instead of wl_buffer_has_alpha().

GLX functions are sometimes directly available in the current binary. In such
cases, we do not need any alternate library loaded using dlopen. Otherwise,
dlopen may find the wrong libGL library and get functions that conflicts with
the current loaded ones.
For example, on Debian Sid with nvidia binary drivers, using mesa's libEGL with
GLX driver leads to wrong glXGetFBConfigs symbol loaded (or loaded twice?),
which leads to "GLX: failed to create any config" error message as the
glXGetFBConfigs symbol seems to return garbage. If the binary is linked with
nvidia's libGL, the GLX symbols are already available.
Without this patch, convert_fbconfig (src/egl/drivers/glx/egl_glx.c:233) fails
for every config found, after glXGetFBConfigAttrib(... GLX_RENDER_TYPE, ...)
call, as the value returned has GLX_COLOR_INDEX_BIT and not GLX_RGBA_BIT.

We don't want to set the pixmap bit in the EGL config if the DRI
config we're adding is a double buffered config. However, don't clear
any other bits the platform might pass in in the surface_type
argument.
Set ctx->WindowRenderBuffer to EGL_BACK_BUFFER. As EGL_WINDOW_BIT of a
config is set only when there is dri_double_buffer, that makes sure
window surfaces are always double-buffered and contexts will render to
the back buffer.

Add platform_android.c that supports _EGL_PLAFORM_ANDROID. It works
with drm_gralloc, where back buffers of windows are backed by GEM
objects.
In Android a native window has a queue of back buffers allocated by the
server, through drm_gralloc. For each frame, EGL needs to
dequeue the next back buffer
render to the buffer
enqueue the buffer
After enqueuing, the buffer is no longer valid to EGL. A window has no
depth buffer or other aux buffers. They need to be allocated locally by
EGL.

but really wtf? all these PCI IDs need to be ripped out of here, its totally

tested by Darxus on #wayland.
If the client hasn't done the initial wl_display_iterate() at the time
we initialize the display, we have to do that in platform_wayland.c.
Make sure we detect that correctly instead of dup()ing fd=0, and use
the sync callback to make sure we don't wait forever for authorization that
won't happen.
When an app loads libEGL.so dynamically with RTLD_LOCAL, loading DRI
drivers would fail because of missing glapi symbols. This commit makes
egl_dri2 load libglapi.so with RTLD_GLOBAL to export glapi symbols for
future symbol resolutions.
The same trick can be found in GLX. However, egl_dri2 can only do so
when --enable-shared-glapi is given. Because, otherwise, both libGL.so
and libglapi.so define glapi symbols and egl_dri2 cannot tell which
library to load.
The idea is to be able to match a driver using the following order
try egl_gallium with hw renderer
try egl_dri2
try egl_gallium with sw renderer
try egl_glx
given the module list
egl_gallium
egl_dri2
egl_glx
For that, UseFallback initialization option is added. The module list
is matched twice: with the option unset and with the option set. In the
first pass, egl_gallium skips its sw renderer and egl_glx rejects to
initialize since UseFallback is not set. In the second pass,
egl_gallium skips its hw renderer and egl_dri2 rejects to initialize
since UseFallback is set. The process stops at the first driver that
initializes the display.
Reorder/rename and document the fields that should be set by the driver during
initialization. Drop the major/minor arguments from drv->API.Initialize.
This is a step forward for compatibility with really old GLX. But the
real reason for making this change now is so that we can make egl_glx a
built-in driver without having to link to libGL.
In preparation for making egl_dri2 built-in. It also handles
symbol lookup error: /usr/local/lib/egl/egl_dri2.so: undefined symbol:

When a context was made current to another surface, the old code did
this
dri2_dpy->core->bindContext(cctx, ddraw, rdraw);

unbindContext should be called only when bindContext is not. This fixes
a regression since d19afc57. Thanks to Neil Roberts for noticing the

The opaque nature of EGLImage implies that extensions almost always
define their own attributes. Move attributes in _EGLImage to
_EGLImageAttribs and add a helper function to parse attribute lists.
We can't expect to have a context when this is called, and we don't need one

This commit introduces type-safe platform displays internally. A
platform display consists of a generic pointer and an enum that
specifies the platform.
An EGLDisplay is created from a platform display. Native displays
become platform displays whose platform is determined by
_eglGetNativePlatform(). Platform windows and pixmaps may also be
introduced if needed.
This extension allows a color buffer to be used for both rendering and
texturing. EGL allows the use of color buffers of pbuffer drawables
for texturing, this extension extends this to allow the use of color
buffers of pixmaps too.
This extension adds a new function which provides an alternative to
eglSwapBuffers. eglSwapBuffersRegionNOK accepts two new parameters in
addition to those in eglSwapBuffers. The new parameters consist of a
pointer to a list of 4-integer blocks defining rectangles (x, y,
width, height) and an integer specifying the number of rectangles in
the list.

egl_xdri steals code from src/glx/x11/. This makes it broken from time
to time when there is a bigger change to the GLX code. As egl_dri2 has
been merged, which also functions as a DRI2 driver loader, remove
egl_xdri for good.
Change _eglInitSurface, _eglInitContext, and _eglInitImage to take an
_EGLDisplay instead of an _EGLDriver. This is a more natural form, and
plus, the display encodes information such as the extensions supported
that might be required for attribute list parsing.
When no context or surface are given, the display is allowed to be
uninitialized. Most drivers cannot handle an uninitialized display.
But they are updated to at least throw a fatal message.
As part of the DRI driver interface rewrite I merged __DRIscreenPrivate
and __DRIscreen, and likewise for __DRIdrawablePrivate and
__DRIcontextPrivate. I left typedefs in place though, to avoid renaming
all the *Private use internal to the driver. That was probably a
mistake, and it turns out a one-line find+sed combo can do the mass
rename. Better late than never.

I don't think anyone besides a developer would ever want to use the demo
egl driver. Furthermore, egl would only ever load demodriver if it was
set via EGL_DRIVER in the environment. In that case, I think you can
point it to your mesa source directory.
This just makes the use of mklib more consistent throughout Mesa where
we always want to pass the linker and LDFLAGS when we might be making a
shared library.
- egl_xdri.c just sets the EGL_OPENGL_ES_BIT as well as the
EGL_OPENGL_BIT in ClientAPIsMask
- eglconfig.c allows the renderable type to include EGL_OPENGL_ES2_BIT
as well as EGL_OPENGL_ES_BIT.
- egl_xlib.c sets the EGL_NATIVE_RENDERABLE attribute to EGL_FALSE for
all softpipe configurations. (Otherwise, an eglChooseConfig() that
looks for particular values of EGL_NATIVE_RENDERABLE will fail.)
Mostly some pedantic changes such that `make clean' always ignores
errors. Also changed the top clean target to do the `touch
configs/current' dance instead of realclean.
