====== std.android.gles2 ======

OpenGL ES 2.0 Bindings für Android: Shader compilieren und linken, Texturen laden, Vertex Buffer Objects erstellen und Draw Calls ausführen. Setzt eine aktive EGL-Surface voraus.

> Die Android-API liegt in ''libandroid.so'' bzw. ''libGLESv2.so''. Für den Aufruf wären ''DT_NEEDED''-Einträge und PLT-Linking nötig, die der Compiler noch nicht erzeugt. Die Quelldatei hält nur Konstanten und Strukturbeschreibungen vor.

Aus dem Kopf der Quelldatei:

> Lyx Android Stdlib - OpenGL ES 2.0 essentials WP-AND-07 The OpenGL ES 2 API surface is huge (~2000 #define values and ~140 entry points); this module ships the subset needed to set up a context, load a shader pair, upload geometry and issue glDrawArrays — the "render-a-triangle" baseline.
