patch to augment SDL_GetError() output from failed EGL calls

If and when SDL calls functions in EGL ( https://www.khronos.org/egl ), and if and when those calls fail, EGL-provideable details on the error may get lost, or become unnecessarily tricky to get information on (client apps would need to call eglGetError() itself, and only on supported platforms).

Attached is a patch that attempts to report EGL error codes, as well as the function which generated them.  It uses eglGetError() ( https://www.khronos.org/registry/egl/sdk/docs/man/html/eglGetError.xhtml ) to retrieve the error, and does so immediately after an EGL call fails.  The function name is listed, as EGL's function-level documentation details which functions generate what error codes, and why.

Comments, questions, or modifications regarding said patch are welcomed!
