Subject: Re: About QNX support in SDL 1.3

Here is another batch of patches.

1) Makefile.in - added SDL_opengles.h header as header to install.
2) configure.in - Added special define to detect Common Lite OpenGL ES
library in case if Common library is not installed. Added check for
clock_gettime in libc (in QNX it is in libc).
3) SDL_config.h.in - Added SDL_VIDEO_RENDER_OPENGL_ES and
SDL_VIDEO_OPENGL_ES declarations for configure script autodetection.
4) SDL_opengles.h - Added GL_API definition if it is not defined. Added
extension GL_OES_draw_texture because OpenGL ES Renderer uses it without
declaration. Added GL_OES_vertex_buffer_object extension, which is supported
under QNX OpenGL ES. Added GL_OES_single_precision extension.
5) To the test directory I've added building OpenGL ES test applications
through the autotools suite. Was support for iPhone IDE building only.
