Packit |
030a23 |

|
|
Packit |
030a23 |
*
|
|
Packit |
030a23 |
* Arguments 'src' and 'mask' contain either a pointer to the top left

|
Packit |
030a23 |
* pixel of the composited rectangle or a pixel color value depending
|
|
Packit |
030a23 |
* on the function type. In the case of just a color value (solid source

Packit |
030a23 |
