data filtering K1900

• modes 2: 16-step gray to 4 step gray
• modes 3: 16-step gray to 2-step gray

data filtering K1901

• modes 2+3: 16-step gray to 4 step gray
• modes 4+5: 16-step and 4-step gray to 2-step gray

rotation on K1900

For mode 01 (90degree) screen resolution is 600x800 and trasmitted as such (i.e. all commands send use this dimension). The epd controller transforms everything to the real dimension of the display (i.e. 800x600).
