- Bug 1135903 - OdinMonkey: Make signal-handler OOB checking an independent configuration r=luke (d9f2104a2) - Bug 1138495 - pt 0 - Reftests for font inflation in vertical writing mode, initially annotated as failing. r=smontagu (6b1a2f47d) - Bug 1138495 - pt 1 - Rename NS_FRAME_IN_CONSTRAINED_HEIGHT flag to NS_FRAME_IN_CONSTRAINED_BSIZE, and set it appropriately according to writing mode. r=smontagu (9d1dfbe3a) - Bug 1138495 - pt 2 - Remove failure annotations from tests that no longer fail; note that the comparison of font-inflation-1c.html vs 1d still fails (they should inflate by different amounts). r=smontagu (1e7a9a2a7) - Bug 1138495 - pt 3 - Compute font inflation based on inline-axis dimensions rather than always using physical width. r=smontagu (d7fc87566) - Bug 1138495 - pt 4 - Remove failure annotation from the final testcase, and add specific equality tests for the correctly-inflated rendering of 1c and 1d. r=smontagu (81de3cb59) - Bug 1132078 - Remove useless null checks after allocating memory with |new| from xpcom/io. r=nfroyd (3c59b0993)
