* each margin, the value specified has the following meaning:
|
|
* -1 - leave the default frame in place
|
|
* 0 - remove the frame
|
|
* >0 - frame size equals min(0, (default frame size - margin value))
|

*
|
|
* This function calculates and populates `mNonClientOffset`.
|
|
* In our processing of `WM_NCCALCSIZE`, the frame size will be calculated

|
* as (default frame size - offset). For example, if the left frame should
|
|
* be 1 pixel narrower than the default frame size, `mNonClientOffset.left`
|
|
* will equal 1.
|
|
*
|
|
* For maximized, fullscreen, and minimized windows, the values stored in
|
|
* `mNonClientMargins` are ignored, and special processing takes place.
|
|
*
|
|
* For non-glass windows, we only allow frames to be their default size
|
|
* or removed entirely.
