Exposed the advanceFrame() function to the Lua API.
There is now an atExit() function in the Lua API to execute a callback when the luastate is exited.
Fixed a couple of rendering issues on the editor.
Some minor changes to how the window is laid out
The GameDB.get() and LocalDB.get()functions now take an optional default value to return if the value searched for was not found. It will return nil if the default value is not specified.
Rengine now has support for PNG graphics!
The bitmap module (bmp.c/bmp.h) now also includes more support for alpha channels, which I needed for a different project, so those functions are there now, but not thoroughly tested or integrated.
Screenshots now save to PNG by default.
