This adds an initLibrary() function to libOpenglRender.
It will be used by the emulator to fallback on software rendering
if the library cannot be initialized properly, e.g. if it is not
possible to load the host EGL/GLES libraries.

This patch changes the filter used to scale the GL window
in the rendering library. Instead of nearest-neighbour, use
bi-linear, which will provide for much more pleasant results
when scaling the emulator UI window, or toggling to full-screen
mode.

This patch modifies GLDispatch.cpp in the translator libraries
to open the Darwin GL library as a framework. Using a hard-coded
system path prevents the requirement to modify LD_LIBRARY_PATH
or DYLD_LIBRARY_PATH to point to the directory that contains the
library.
In this specific case, this is equivalent to
/System/Frameworks/OpenGL.framework/Libraries/libGL.dylib
But is the "kosher" way to open it the library.

These libraries are only used by libOpenglRender, so make them
static so that their code is included in this shared library
instead. This reduces the shared library dependencies that
will be required from the emulator.

add drawValidate when calling glCheckFramebufferStatus
in the draw validate, a color attachement will be added to the
framebuffer if there is no target attached to COLOR_ATTACHMENT
of the framebuffer.
opengl does not allow framebuffer with no color attachement
so CheckFramebufferStatus would return INCOMPLETE status.
We already call drawValidate before any draw, the call was
missing at glCheckFramebufferStatus.

There is a flashing effect we see on Mac when switching between
drawables (pbuffer and a window) on the same context.
This change make the FrameBuffer object in the renderer to use
two different OpenGL contexts, one which is used while the pbuffer
drawable is bound and another which is used when the subwindow is
bounded during swap. The two contexts share textures so both contexts
have access to all allocated color buffers.
While this fixes the flashing effect on Mac, it should be more effective on
other platforms as well.

This change removes the 'blitFromPbuffer' path in the renderer
which uses binding pbuffer to texture. This path does not work
on all platforms and is not relavent any more. It simplifies
a lot the FBConfig filtering code.
Also, added a check to fail the renderer initialization if
the translator plugin does not support EGL_KHR_gl_texture_2d_image
and GL_OES_EGL_IMAGE (by both GLES implementations [1 and 2])
since our implementation requires it.

This is a workaround to a driver bug on Intel/Linux, when destroying
a subwindow do not close the X display connection, keep it for the
next call to createSubWindow. It happens that the intel/linux driver
caches the display connection for each window ID and use it during
swap or something similar. Using the same display connection for
all subwindows workaround the problem.
Also added a wait loop to wait until the window becomes mapped
instead of just calling XSync after calling XMapWindow. This
is more accurate and make sure we do not miss the first window
refresh.

on eglCreateContext the translator created a window for the
specified config with a matching pixelformat and saved it's
device context for future use.
however when the thread exited the window was destroyed by windows
and the handle saved became invalid.
the next call to wglCreateContext with the handle saved failed.
fixed the problem by creating windows per thread and not in a
global pool.
each thread will create its own window for each config when asked
the window will be destroyed when the thread exits.

Changes the render_api to support re-creating the display
sub-window and the ability to rotate the displayed framebuffer
image.
That currently works only when the renderer runs as a thread
and not as seperate process. Therefore we setup the library
to run the renderer as thread(s) inside the calling process
on *all* platforms for now.

On Mac it happens that when a context is bound to a pbuffer
and you want to bind it to a window (NSView) instead you must
release it from the pbuffer before binding the window by calling
clearDrawable handle of NSOpenGLContext.
This change added an override of NSOpenGLContext in order to track
to which drawable type the context was previously bound and
call clearDrawable when necessary.

Workaround to intel/linux driver issue.
Desktop OpenGL does not support precision qulifiers in shaders,
so we remove them by defining "precision" "mediump" "lowp" and
"highp" to blank.
That translates the line "precision mediump float;" to "float;" which
is a valid command according to the GLSL spec however it fails
to compile using the intel/linux driver.
This change adds a parser which removes completely the
precision command from the shader source.

In GLES, a vertex shader attribute can be at location 0 and have
a current value. In OpenGL, the spec is not clear, resulting in
absurdities like the ATI driver binding an attribute to location
0, does not give an erro when you set it, but gives an error when
you try to get it back. And it doesn't actually set the value in
the shader.
So, in this patch we:
1. Track attribute 0 value internally, setting and getting it
as necessary.
2. Upon glDrawArrays and glDrawElements, if attribute 0 is not
"array enabled" (that is, it should use a current value) we
create a dummy array, fill it with the intended current value,
and attach and enable it. After the draw, we disable it.

The GLES and OpenGL specs for glFramebufferTexture2D are different, which
caused valid GLES calls to fail when moved over to OpenGL. Specifically,
a framebuffer in OpenGL must have a color attachment in order to be valid
for draw, while in GLES it doesn't. So add a validate function, and call
it from each drawing API call.
This patch also contains a workaround for a bug in the ATI driver, where
changing the framebuffer attachments requires a rebind of the framebuffer.

Removed calling into opengl/wgl from the initialiation code
of libEGL (was made during creation for the EglGlobalInfo object
during global variable initialization) !
That causes issues on ATI driver on windows since we might call into

during the first call into libEGL.
Also ATI's version of wglChoosePixelFormatARB does not accept
NULL in the attribute list arguments.

Handling clean exit of the renderer when stopOpenGLRenderer
is called. This is done by openning a connection to the renderer
and flag that it should exit. Added 'clientFlags' field which must
be send after every connection is made to the renderer for this purpose.
The server will wait for running rendering threads to exit and then will
close all EGL/GL resources and will exit. The stopOpenGLRenderer will
return only when the renderer has exited.

GLSL ES 1.0.17 spec states that its written against
OpenGL GLSL version 1.2, that means that #version 100

GLSL.

higher version has been requested in the shader source
or when GOOGLE_GLES_FORCE_GLSL_VERSION is defines.

That adds support to create a renderbuffer storage from an EGL
image (previously only texture was supported).
For that we have added Renderbuffer and Framebuffer attachment points
state tracking and when a renderbuffer which attached to an EGLImage

texture instead.
