* margins and fires off a frame changed event, which triggers an nc calc
|
|
* size windows event, kicking the changes in.
|
|
*
|
|
* The offsets calculated here are based on the value of `mNonClientMargins`
|

* each margin, the value specified has the following meaning:
|

* 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
