+ * Decode texture data in format `MESA_FORMAT_ETC1_RGB8` to

+ *
+ * The size of the source data must be a multiple of the ETC1 block size,

+ * From the GL_OES_compressed_ETC1_RGB8_texture spec:
+ * The texture is described as a number of 4x4 pixel blocks. If the
+ * texture (or a particular mip-level) is smaller than 4 pixels in
+ * any dimension (such as a 2x2 or a 8x1 texture), the texture is
+ * found in the upper left part of the block(s), and the rest of the
+ * pixels are not used. For instance, a texture of size 4x2 will be
