Alternative scale method for overloading.

A derived class can implement alternative scaling algorithms by overloading this method and returning true if alternative scaling has been performed.

Parameters
srcDataThe source image data.
dstDataThe destination image data.
srcPixelSizeXThe number of horizontal source pixels.
srcPixelSizeYThe number of vertical source pixels.
srcBytePitchThe number of source bytes per line.
dstPixelSizeXThe number of horizontal destination pixels.
dstPixelSizeYThe number of vertical destination pixels.
dstBytePitchThe number of destination bytes per line.
pixelFormatThe pixel format.
gammaThe gamma value. Specify 1.0 to disable gamma correct scaling.
Returns
false if fast scaling is not supported.

Reimplemented in Murl::Util::BoxVideoScaler.
