added state tracking for uniforms in program objects
for each active uniform in index i we will save its starting location
,size and type, so when calling glGetUniform on its location,
we can tell how many bytes we should read from the stream according to
the uniform's type
add some type and size definitions to functions
that calculate size from enum
some other fixes to the codec

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
the driver before it gets initialized. Instead we initialie the EglGlobalInfo
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
in GLSL ES should be mapped to #version 120 in OpenGL
GLSL.
We now force "$version 120" in all shaders except if
higher version has been requested in the shader source
or when GOOGLE_GLES_FORCE_GLSL_VERSION is defines.
(Note that GOOGLE_GLES_DEFAULT_GLSL_VERSION is renamed
to GOOGLE_GLES_FORCE_GLSL_VERSION).
That fixes "Aqua Slash GL Demo" application !!

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
get attached to a framebuffer we attach the underlying EGLImage's
texture instead.
Also fixed some egl_image related bugs.
That makes the egl_image conformance test to pass on host.

We save the texData->target in original format, but use our internal format
(using GLTextureTargetToLocal) to make sure we're not mixing 2D and CUBE_MAP textures on
glBindTexture.
Also added the GL_S/R/T/Q constants where needed.
This fixes the Cube Map test in Api Demos.

texture=0 has a special meaning - detach texture. Therefore we should pass

eglGetProcAddress should return a function pointer that does not
depends on the current bounded context (if any), when the user
calls one of the function pointers returned from eglGetProcAddress
for one of the GLES extension functions, the GLESv1 or GLESv2
version of the extension function shold be called depending on
the current bounded context.
For this we have added a ClientAPI (GLES) extension dispatch
table in the EGL level which points to static functions in libEGL
where each function checks in runtime the current bound context and
calls down to the GLES_CM -or- GLESv2 library function.
See ClientAPIExts.cpp, when new GLES extension functions are added
to GLESv1 or GLESv2 its definition should be added to
ClientAPIExts.in as well.
This fixes the segfault in egl_image conformance test.

Handle EGL context and surfaces destrouction using ref counting
pointer (SmartPtr) rather then maintaining a "markForDeletion" flag.
This has required to re-arrange the ThreadInfo structure to be local
to EGL rather then in the GLcommon area so that we will be able to
place a ref-counted pointer to the current context in the TLS.
That fixes the crash during exit of covgl conformance test.

The was a bug in the calculation of the pixels data size, caused by wrong usage

This is needed to support the rare, but still legal scenario,
when glDrawElemets is used with some index array data is stored in VBO's
while the actual attributes (vertices) data is in immediate mode.
When in immediate mode, we need to process the incodes, in order to know
which vertex data to send, which was impossible without the caching.
This commit introduces a new class GLSharedGroup, which will hold all data
that can be shared by shared contexts (buffers are such data).
This also makes the "Jet Cars Stunts" app work properly.

In case we're receiving packets larger then the initial size

This change modifies the function declarations under
developement/tools/emulator/opengl/host/include/render_api.h
to make them callable from C.
This is preparation work for integrating the rendering library
into the emulator. The plan is to dlopen() the library dynamically
and using non-mangled function names makes using dlsym() both
easier and more portable.

Adds GLSL built in constants defined in GLSL ES but not in GLSL.
Makes biConstant conformance test to pass on Mac (where ES2_compatability is not
present).
Also fixed the GLSL parser to insert our additions to the shader
only after the "#version" token if exist in the original shader.
Also renamed env var GOOGLE_GLES_FORCE_GLSL_VERSION to
GOOGLE_GLES_DEFAULT_GLSL_VERSION to better match its functionality since
we use it only if no specific version exist in the shader code.

This is not really a bug, but the nVidia shader compiler is much more
liberal than the GLSL spec, and allows compilation of shaders which
do not comply with the spec. This is an issue for passing the
conformance tests, but more importantly it will allow bad shader written
by the app developer to pass on the emulator and then to fail on the device.
Adding "#version 100" definition to the head of a shader source disables
this liberal behavior. For now this is activated in run time by the "NV_WAR"
environment variable.

Do not allow glLinkProgram to succeed if only one shader type has been
attached to the program, GL allows this, but GLES2 does not.
added state tracking for program objects to check which shaders are
attached to the program object.

Instead of calling the dispatcher directly. This will make sure all Translator's
internals (such as TextureData data) are updated properly.
This also fixes the bug in "Replica Island" - when the green robot was invisible,
because it's TextureData wasn't updated by doCompressedTexImage2D
The pointer to glTexImage2D is passed as a parameter to doCompressedTexImage2D,
otherwise Windows resolve the glTexImage2D symbol in the external libGL rather
than the translator's code. Longer term, we will remove the translator's link
to libGL, at which point this parameter will be removed.
The getGlobalName function returns 0 on error. There are many places
were no error checking is done after calling it to get a shader or
program name. Typically this shouldn't be an issue, since the follwing
OpenGL call using a value of 0 will generated the required GL_INVALID_VALUE,
but this does not always happen.

in Windows platform we previously defined EGLNativeDisplaytype to be WinDisplay*
( this was defined in include/EGL/eglplatform.h) this was OK as long as we used the
the EGL_DEFAULT_DISPLAY as parameter for eglGetDisplay meaning we were generating
a native display by oureselv and wrapping it, but there was aproblem when we got the
EGLNativeDisplayType from the user (as HDC in Windows) but interpret it as WinDisplay*
this caused a big memory corupption.
so to overcome this problem we now define two types EGLNativeDisplayType to be
HDC and EGLNativeInternalDisplayTypeto be WinDisplay*, and when we get in eglGetDisplay
a parameter different from EGL_DEFAULT_DISPLAY we wrap it with the struct of WinDisplay
and return it to the user.
this change caused a change in all the declerations of EglOsApi.h changing
EGLNativeDisplayType -> EGLNativeInternalDisplayType

This commit does few things:
1. Gets doCompressedTexImage2D out of the context and TextureUtils
2. Gets palette textures out of TextureUtils and into PaletteTexture
3. Makes TextureUtils generic for all compressed textures
4. Moves the glGet's dealing with compressed textures from GLEScontext to the impl.
