Improve image size validation in CPDF_ScaledRenderBuffer.
In CPDF_ScaledRenderBuffer::Initialize(), use the existing CFX_DIBitmap::CalculatePitchAndSize() function to figure out the pitch and size. Unlike the existing code, CalculatePitchAndSize() does a better job of checking for integer overflows.
