gint 2.8 image things:
|
||||
* Margins around the VRAM, and around XYRAM fragments
|
||||
* Design the new image formats, inspired from libimg
|
||||
* Replace the [profile] attribute with [format]
|
||||
* Single VRAM
|
||||
|
||||
Extensions on existing code:
|
||||
* usb: add PC->calc reading, and interrupt pipes
