Implemented validation for loop and indexing limitations specified by GLSL ES spec 1.0 Appendix A Section 4 and 5.
A couple of things to note:
- This CL only validates the "form" of loop and indexing. It does not detect number-of-iterations or out-of-bound access. This will require more involved analysis/heuristics.
- I haved combined SH_VALIDATE_CONTROL_FLOW and SH_VALIDATE_INDEXING into one flag - SH_VALIDATE_LOOP_INDEXING. Validating both together is much easier.

glGenerateMipmap now does not force textures to become render targets.
For textures that are not already render targets, use the CPU to filter them and mark them as dirty.
I tested it by modifying the "mip_map_2d" demo to call glGenerateMipmap instead of generating the mipmaps itself. I also used the debugger to force it to take the render target path and verified that it still worked.
We've been having problems with the display being reset when video memory pressure is heavy with one of our demos. This patch made a noticable improvement on Vista but I don't think it will necessarily help on XP.

Moved the global-pool-allocator to TCompiler so that all memory allocated by the compiler can be de-allocated. Earlier the global-pool-allocator kept accumulating memory from all compilers (symbol-table in particular). The memory was only de-allocated when gpu-process exited or ShFinalize() was called. This was a problem for Chromium which keeps the GPU process around for the browser session. Now the memory is de-allocated as soon as the compiler is deleted, which happens when a tab is closed.

Made GL_RGB textures map to D3DFMT_X8R8G8B8.
I suspect there is a subtle reason why this is the wrong thing to do.
The issue I am trying to address is glBlitFramebufferANGLE generating an error when bliting from a GL_RGB8_OES renderbuffer to a GL_RGB texture bound to the read framebuffer and draw framebuffer respectively. It verifies that both surfaces have the same underlying D3DFMT but GL_RGB8_OES renderbuffers are backed by X8R8G8B8 and GL_RGB textures were previously backed by A8R8G8B8.
Since textures cannot as far as I know be created GL_RGB8_OES, it would be useful to have a way to blit from a GL_RGB8_OES renderbuffer to a GL_RGB texture.

Only initialize through a temporary variable if the same symbol name is used in the initialization expression.
TRAC #13627
The previous patch can generate a lot of unnecessary temporary variables. By first checking whether the same symbol name is reused the clutter is reduced to an absolute minimum (typical shaders won't rely on this odd GLSL semantic behavior so the workaround is hardly ever needed).

GLSL allows to write things like "float x = x;" where a new variable x is defined and the value of an existing variable x is assigned. HLSL uses C semantics (the new variable is created before the assignment is evaluated), so we need to convert this to "float t = x, x = t;".

Refactored glslang grammar files to make:
- lexer and parser reentrant
- line number handling automatic
Caveats:
- The preprocessor is still not thread-safe and full of bugs. I have another not-yet-ready patch to replace the preprocessor.
- The grammar files use options that are not supported by the old versions of flex and bison checked into compiler/tools. So I need to check-in the generated lexer-parser along with a shell script to generate them.

Fixed infinite loops and buffer overflow in byte_scan when scanning for integers and floating-point numbers.
- The byte_scan and associated functions are not very well written. I tried to clean them as much as possible without re-writing the whole thing.
- Replaced lBuildFloatValue function with atof. lBuildFloatValue was returning incorrect value anyway. The only reason it was working so far because we never used that value.

eglCreateContext checks client version is 2.
I believe we don't support version 1 since we are missing things like the fixed function pipeline.
This is motivated by consistency with other EGL implementations, which return a v1 context if the EGL_CONTEXT_CLIENT_VERSION attribute is not specified.

Add proper detection for maximum texture and renderbuffer size
Trac #13849
Increased the maximum possible texture & renderbuffer size to 16384 (the minimum required for DX11 cards).
Limit the actual maximum texture & renderbuffer size to the maximum
that it reported by the underlying D3D9 device.
Note that creating textures and renderbuffers at the maximum size will quickly exhaust video memory!

It's crashing upon creation of the GL context, possibly the first context. Device lost would possibly explain the XP crashes. The Windows 7 box might have run out of video memory.

It was a Windows XP service pack 3 box with Chrome 7.0.524.0. ANGLE was at r418 in this build. I suspect it attempted to glClear after a device lost, which caused needsRenderTarget to fail.
This will hopefully patch it up so it doesn't crash. We'll need to check we aren't assuming mTexture is not null elsewhere.

I suspect there is a bug whereby an owning reference to a RefCountObject is temporarily assigned to a BindingPointer, causing it to be destroyed and making the owning raw pointer go dangling.

Replaced raw pointers to RefCountObject to BindingPointer.
This fixes the ANGLE crashes in Chrome when using canvas 2D.
The issue was this:
Renderbuffer *mColorbufferProxy = new RenderBuffer(...); // Reference count is zero.
BindingPointer<RenderBuffer> tempRef;
tempRef.set(mColorbufferProxy); // Reference count is one.
tempRef.set(NULL); // Reference count is zero and object is destroyed, leaving mColorbufferProxy dangling.
I also initially suspected the problem was that FBOs are not treated as shared and the implementation of shared FBOs is still in the patch. I believe GLES2 supports shared FBOs.
My reading of the GLES2 spec is that when a shared object is deleted, it loses its id but retains its state if left bound elsewhere. I added that to RefCountObject.

Replaces swap chain lazily when the swap interval is changed.
It does not appear to be possible to pass a presentation interval to Present() or change it after creating the swap chain, short of calling Reset(). I decided to try fixing it by replacing the swap chain under the same conditions as a window resize.
I tested it with a modified version of the simple vertex shader sample, passing various values to eglSwapInterval.
My reading of the EGL spec might be wrong but I believe the interval state should be associated with the surface bound to the current context, rather than the display.

Implemented GL_NV_fence extension.
I believe I have implemented all features according to the spec.
The application is to allow the Chrome command buffer scheduler to be smarter about deciding which command buffer to process. For example, if a WebGL app issued a call to ReadPixels, the scheduler will issue a fence and defer executing the ReadPixels until the status goes true. It can continue to work on other command buffers in the meantime.
I tested by modifying the vertex shader demo. After issuing the SwapBuffers i made issue a fence and loop until the status went true and verified it looped several times. I also tested that by calling FinishFence before going into the loop that is did not loop at all.

Adding support for OES_standard_derivatives extension. This is not the complete implementation. Sending it to get feedback on the API. Is it OK to add extension support into TBuiltInResource? I could create a new struct for extensions but that would lead to API change.

Changed glFlush to not wait until issued event is processed.
I think these reduced synchronization guarantees are still compliant with the spec. I found that this significantly improved the frame rate for some of our demos (40 fps to 50fps for one on my box). I will change the demo so that it does not call glFlush at all but I still think this is a valuable change.
The OpenGL ES2 spec says:
"The command
void Flush( void );
indicates that all commands that have previously been sent to the GL must complete in finite time."
My reading of it is that any GL calls previously issued will be processed at some point in the future but not necessarily prior to glFlush returning. I believe that issuing the D3D event and then calling GetData once with the flush flag should meet these requirements.
I also added some assertions to glFinish because I was paranoid that if issuing an event ever failed, the spin loop might never terminate.

Implements a special case for temporary surface creation for DXT low mip levels.
TRAC #12908
The lowest mip levels for DXT textures will have dimensions < 4, so a D3D
texture cannot be created to hold them offscreen directly. Instead, we must
create a larger texture one of whose mip levels would be the desired dimension,
and store the surface from that texture for later inclusion in the final
texture.
