During June and July 2017 I have been working as usual, in my spare time, on the project. 😉
The first big June addition has been the automatic screen culling of sprites, a very important feature needed in order to support games extending on multiple screens. The culling works on sprites of any kind (regular ones, particles, text nodes) and regardless of their scaling or rotation parameters. If those sprites are completely outside of the screen they will just not be rendered, saving draw calls from being issued.
