FrameBuffer
@RequiresApi(value = 26)
class FrameBuffer : AutoCloseable
Object that enables rendering into a HardwareBuffer by creating a frame buffer object from it by leveraging Android specific EGL extensions to create an EGLImageKHR object that is loaded as a texture.

Public functions
close
open fun close(): Unit
Closes out the frame buffer, freeing all resources within it. This should be done only when the frame buffer is no longer needed or being accessed.
makeCurrent
fun makeCurrent(): Unit
Binds this frame buffer to the read and draw framebuffer targets if it's not closed. If the frame buffer is already closed this method will do nothing.
