+Interface Overview</title><shortdesc>The EGL Interface component defines the interface to EGL on the

+EGL implementers. </shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>

+<section><title>Header files</title> <p>The EGL Interface component includes
+the Khronos-released header file, <filepath>egl.h</filepath>, and <filepath>egltypes.h</filepath>,
+which is the Symbian equivalent of the Khronos <filepath>eglplatform.h</filepath>.
+Use of the header files supplied in the EGL Interface component helps to ensure
+binary compatibility for applications across different Symbian platforms.
+It also provides source compatibility between different operating systems.
+These header files incorporate minor changes such as Doxygen tags (/** comments)
+but these have no effect on the functionality. </p> <p>The header files are
+provided for EGL 1.2, 1.3 and 1.4. The EGL 1.4 headers are used by default.
+However, there is a variability point that can expose the headers for EGL
+1.3 or 1.2 instead. </p> <p>The Symbian-defined header file <filepath>\epoc32\include\khronos_types.h</filepath> maps
+the Khronos-defined basic types to native Symbian types. </p> </section>
