[EFL] Implementation of missing functions in GraphicsContext3DPrivate

[Hyowon Kim]

The implementation of GC3DPrivate has splited into three patches in order to keep it simple and short.

1. Bug 62961 is the initial implementation including simple functions which only call GL functions through Evas_GL_API.

2. This patch contains the implementation of a little complicated functions such as getActiveAttrib(), getShaderSource() and so on.

3. The last patch for GC3DPrivate is going to include initialization and destruction using Evas_GL APIs.

LGTM, except a couple of nitpicks - please fix before committing.

Use .isEmpty()

> Source/WebCore/platform/graphics/efl/GraphicsContext3DPrivate.cpp:463
> +        *value /= 4;

Comment for why this is /4

It's a really important finding!

I was a little confused about OpenGL ES 2 compliance.

Evas_GL offers the OpenGL ES 2 interface, so I removed codes for desktop-GL in getIntegerv() like GraphicsContext3DOpenGLES.cpp.

Please review this modification again. Thanks.
