Enabling ParentFont for forms in BCB11 broke scaling. VCL does not enable ParentFont for new forms either. Also with ParentFont enabled, designing on scaled display does not work correctly.

Fixing some anchors and tab order on the way
Dialogs (and controls with specific width or height) are now about 10% wider
Note that main form already used the Segoe UI:9 by explicitly using UseDesktopFont for most/all of its controls
Layout rules
- follow IDE design guidelines in general
- controls start at 8x8, but at 9x9 in group boxes and 22v if group has title
- right and bottom padding in groupbox is the same as left padding
-for checkboxes the bottom padding of the checkmark is the same as left padding = 10
- buttons are 80x25 by default, with +14v with dropdown
- checkboxes/radiobuttons are +2h
- labels are 15 high, textboxes/comboxes 23
- indentation is controls under checkboxes is +16h

– Control's Canvas does not have Font updated when painting, so it needs to be set explicitly in some places
– Page control drawing was not only incompatible, but broken in general, so it was refactored – giving up on trying to make it 100% mimic system drawing
– CM_DPICHANGED replaced with OnAfterMonitorDpiChanged for form-level scaling. Not really necessary, just for style. Though it is not called for initial resize (at least when starting on primary monitor with temporary non-system DPI)
– OnResize is not called for DPI change, so in some instances, some OnResize call was duplicated in OnAfterMonitorDpiChanged/CM_DPICHANGED
– Scaling of thirdparty box still does not work correctly (but Updates box works??)
– Scaling on primary monitor with temporary non-system DPI is bad
– TTreeView enabled DPI scaling when using Images that is not Scaled
– Discaring obsolete FSiteButtonsPadding workaround
– Controls programmatically added to form are automatically scaled to the form's DPI (relevant for message boxes)
