Font textures disappear, caused by glDeleteTextures on main thread

[tdanyluk]

Hello Saki!
Thanks for the excellent library!
However on the One Plus One phone i discovered that the font textures in the app disappear after pause/resume (changing app).
Like this

I think the problem is that glDeleteTextures is called in the main thread.
CameraSurfaceRenderer.onSurfaceDestroyed is called in the main thread.

Changing its code solves the problem:
This way it is good:

	public void onSurfaceDestroyed() {
		if (DEBUG) Log.v(TAG, "onSurfaceDestroyed:");

		GLSurfaceView parent = mWeakParent.get();
		parent.queueEvent(new Runnable() {
			@Override
			public void run() {
				if (mDrawer != null) {
					mDrawer.release();
					mDrawer = null;
				}

				if (mSTexture != null) {
					mSTexture.release();
					mSTexture = null;
				}

				GLDrawer2D.deleteTex(hTex);
			}
		});
	}

The error no longer happens however i am not sure that this is the best solution.
I would appriciate your kind help.

Best regards
Tamás

I also met with this problem on some types of Xiaomi when hardware accelerated is set to true. Thanks to your solution, it seems to work well now!
