* Fix calling (and checking) the decal_ functions when the input is ↵Gravatar reed@google.com2012-06-13
| | | | | | | | | | | | | SkFractionalInt. The bug was to cast to SkFixed from SkFractionalInt, when what we needed to do was shift the fractional guy down to fixed. This bug was only caught on an android device w/o neon, since other configs have assembly for their matrixproc that didn't have this bug.

* We were numerically overflowing our 16bit coordinates that we communicateGravatar reed@google.com2012-05-03
| | | | | | | | | | | | | between these two procs. The fixes was in two parts: 1. Just don't draw bitmaps larger than 64K-1 in width or height, since we can't represent those coordinates in our transport format (yet). 2. Perform an unsigned shift during the calculation, so we don't get sign-extension bleed when packing the two values (X,Y) into our 32bit slot.

The scale versions, because they operate in a scaled 65535 space, are not always exact for large images (due to SK_Fixed1 / width) loss of bits git-svn-id: http://skia.googlecode.com/svn/trunk@320 2bbb7eff-a529-9590-31e7-b0007b416f81
