2016-11-04Assert objnum non-zero in ReplaceIndirectObjectIfHigherGeneration()tsepez
Removes a path where it might not have taken ownership of an object, at the expense of making callers check first. This eases making the second argument an unique_ptr someday. Review-Url: https://codereview.chromium.org/2475823002

An optimization to speed up float-to-int rounding caused a different result for one input value.

2016-10-28Use CompositeMask instead of TransferBitmap when drawing type 3 textnpm
TransferBitmap seems to work improperly when the glyph boxes overlap. In particular, after drawing a glyph, the next glyph's blanks will override what the previous glyph drew, and this is not the correct behavior. While on it, use CheckedNumeric to do operations safely.
