scalerFeatures

Mask of scaling features.

Declaration

IOOptionBits scalerFeatures;

The following are defined:

`kIOScaleStretchOnly`	If set, the framebuffer can only provide stretched scaling with non-square pixels, without borders.
`kIOScaleCanUpSamplePixels`	If set, framebuffer can scale up from a smaller number of source pixels to a larger native timing (eg. 640x480 pixels on a 1600x1200 timing).
`kIOScaleCanDownSamplePixels`	If set, framebuffer can scale down from a larger number of source pixels to a smaller native timing (eg. 1600x1200 pixels on a 640x480 timing).
`kIOScaleCanScaleInterlaced`	If set, framebuffer can scale an interlaced detailed timing.
`kIOScaleCanSupportInset`	If set, framebuffer can support scaled modes with non-zero `horizontalScaledInset, verticalScaledInset` fields.
`kIOScaleCanRotate`	If set, framebuffer can support some of the flags in the kIOScaleRotateFlags mask.
`kIOScaleCanBorderInsetOnly`	If set, framebuffer can support scaled modes with non-zero `horizontalScaledInset, verticalScaledInset` fields, but requires the active pixels to be equal in size to the inset area, ie. can do insets with a border versus scaling an image.
