* NOTES
|
|
* If LR_CREATEDIBSECTION is absent, the copy will be monochrome for
|
|
* a monochrome source bitmap or if LR_MONOCHROME is present, otherwise
|
|
* the copy will have the same depth as the screen.
|
|
* The content of the image will only be copied if the bit depth of the
|
|
* original image is compatible with the bit depth of the screen, or
|
|
* if the source is a DIB section.
|
|
* The LR_MONOCHROME flag is ignored if LR_CREATEDIBSECTION is present.
