Initialize colour valueschromium/3080
The colour values returned from the ColorSpace GetRBG methods may not have set a value. This CL updates the CPDF_MeshStream to always initialize the values to 0 so they can't be used uninitialized. Bug: chromium:714074 Change-Id: Id2db5eabe31d2ff19f9330b2bc5c681680cf461d Reviewed-on: https://pdfium-review.googlesource.com/4450 Reviewed-by: Tom Sepez <tsepez@chromium.org> Commit-Queue: dsinclair <dsinclair@chromium.org>
