Values for SetImageScaling / GetImageScaling and for the imageScaling field on SFTBUTTON_CONTROL.
| SFTBUTTON_IMAGESCALING_ASIS (0) | Images are drawn at their native pixel size. |
| SFTBUTTON_IMAGESCALING_STRETCH (1) | Default. Images are scaled by currentDPI / 96. Bitmaps use HALFTONE stretch; GDI+ images use InterpolationModeHighQualityBicubic. |
imageScaling is independent of pixelScaling - either can be set to ASIS or STRETCH without affecting the other.
