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.
