The Nvidia Tegra 3 driver for Android (used by Ouya) erroneously claims
to support the desktop-oriented GL_EXT_texture_array extension. On
desktop GPUs using (non ES) OpenGL, the glTexImage3D and similar
functions are always present, and the GL_EXT_texture_array extension
simply adds support for texture arrays to those functions. On OpenGL ES
2.0, those functions do not exist, and GL_OES_texture_3D is required to
define them.
Calling glTexImage3D on the Tegra 3 causes a segfault. This change works
around the issue by manually setting GLAD_EXT_texture_array to 0 on
OpenGL ES 2.0 systems, which causes LÖVE to avoid codepaths that assume
that the 3D texture functions are available. It doesn't make sense for
any OpenGL ES 2.0 GPU to claim support for GL_EXT_texture_array.
