 * `Zones` will now use the new `customHitArea` property introduced in 3.17 to avoid their hit areas from being resized if you specified your own custom hit area (thanks @rexrainbow)
 * The default `BaseShader` vertex shader has a new uniform `uResolution` which is set during the Shader init and load to be the size of the Game Object to which the shader is bound.
 * The default `BaseShader` vertex shader will now set the `fragCoord` varying to be the Game Object height minus the y inPosition. This will give the correct y axis in the fragment shader, causing 'inverted' shaders to display normally when using the default vertex code.
