If the bitmap doesn't fit on the display at this location, nothing is drawn at all.<br/>
|
|
Unset pixels are treated as transparent <br/>
|
|
This function is by far the most tricky piece of code in this project,<br/>
|
|
don't worry if you don't understand it at first sight. <br/>
|
|
Actually it just loops bitwise through the bitmap and uses some <br/>
|
|
nice bit shifting magic to get it anywhere you want.</p>
