Snapshot 2.99.906 (2013-11-13)
Several stability fixes required after the recent tweaking of the core
mechanics to handle the updated TearFree and attempting to make static
analyzers happy.

 * Fix damage handling when rendering to a partially damaged GPU surface.
   Regression in 2.99.905

 * Use asprintf() instead of sprintf()
   Regression in 2.99.905

 * Improve accounting for fence overallocation on older gen2/3, and
   improve the tiling mechanism to fit into the same aperture constraints

 * Add an extra GPU flush on Sandybridge to fix some rare font corruption

 * Rasterise lines through all clip boxes

 * Fix regression from stricter handling of failures to move a GC to the GPU
   Regression in 2.99.905

 * Fix various fail along the memcpy_xor paths, including inadequate error
   handling and integer overflow

 * Fix outside-of-target stipple uploads

 * Fix clip detection for long glyphs
   Incomplete bug fix (causing a regression) in 2.99.905

 * Fix VSync for the render engine (Xv) on Haswell
