NOTE: UNDER ACTIVE DEVELOPMENT - THERE ARE BUGS/GLITCHES
|

|
||||
What is this?
|
||||
~~~~~~~~~~~~~
|
||||
This extension provides drawing routines that are compatible with
|
||||
changeable world and screen spaces. For example you can pan and
|
||||
zoom, and all PGE drawing routines will automatically adopt the current
|
||||
world scales and offsets.
