* The total BMP area starts at 0x***80008 or 0x***00008 and has 960x540 pixels.
*
* Normally, only the center part (720x480) is used. So, Canon BMP functions
* will return a pointer with an offset equal to 30*960 + 120 => VRAM address will end in 0x7100.
*
* End of BMP VRAM is at 0x***80008 + 0x7E900 (960x540). It's not safe to write past this address.
*
* The problem is that HDMI properties are not reliable for telling HDMI size
* (race condition while changing display modes).
*
* Workaround: ML will always use a pointer to the CROPPED (720x480) BMP VRAM.
*
* Advantages:
*
* - Zero chances to write past the end of the VRAM due to race condition when changing display modes
* - Everything you draw on the screen will be visible and centered well on HDMI
* - Keeps most of the existing code (designed for LCD) unchanged
*
* Disadvantage:
* - On HDMI, you may have to draw BEHIND the VRAM pointer (you can go at most 30 lines and 120 columns back).
* Could be a bit ugly to code.
