/**
|
|
* A WebGLBatch Enables a group of sprites to be drawn using the same settings.
|
|
* if a group of sprites all have the same baseTexture and blendMode then they can be grouped into a batch. All the sprites in a batch can then be drawn in one go by the GPU which is hugely efficient. ALL sprites in the webGL renderer are added to a batch even if the batch only contains one sprite. Batching is handled automatically by the webGL renderer. A good tip is: the smaller the number of batchs there are, the faster the webGL renderer will run.
