Allow derivative functions if derivative extension is enabled. I still need to add validation for "#extension GL_OES_standard_derivatives : enable".

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.

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.

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.

TIntermBinary::promote() was incorrectly marking the type of result as const in some cases. The result can only be const if both operands are const. Also cleaned up the function to remove redundant/repeated checks.

This fixes the crash on lost context for vista and windows 7 if suitable drivers are available. It now uses D3D9Ex when available and this only reports lost contexts for hardware failures and suchlike.

Testing procedure was:
- run simple_vertex_shader without this change.
- ctrl+alt+del to lock machine.
- return to desktop.
- observe that simple_vertex_shader crashes.
- repeat with this change and check that simple_vertex_shader is still animating.
- simulate the code path that an XP machine would take using the debugger and check that old behavior is preserved.

I decided to load D3D9.DLL at runtime for a couple of reasons. First, I didn't want to assume that older implementations of D3D9 would have the Direct3DCreate9Ex entry point. Second, it might be advantageous for some applications to not have a load time dependency on D3D9. I didn't address this for D3DX9 because it's a little harder - there's no clear way to determine which D3DX9_x.DLL library to open. At least D3DX9_x.DLL does not seem to import D3D9.DLL and D3DX is separately redistributable so there is still some advantage to be had.
