Skia Merge (revision 1510)
This CL includes bug fixes and closely mirrors the version of
Skia used in Chrome M13, which is likely to be our baseline for
ICS.
The CL also adds source files for the SampleApp which will allow
us to execute basic skia tests. The SampleApp requires the
utils/views directory in order to run.
Finally, we have included the PDF backend for Skia in order to
experiment with using it to generate PDF files for certain
applications.
Note: The SampleApp and PDF code are not built as part of libskia.

+Building the sample app for Android using an Android tree:

+Copy this folder into an Android tree in packages/apps. In addition to jni,

+will include the skia files which are not part of an Android checkout. It
+should have three folders: include, samplecode, and src.

- # Due to an unfortunate intersection of lameness between gcc and gyp,
- # we have to build the *_SSE2.cpp files in a separate target. The
- # gcc lameness is that, in order to compile SSE2 intrinsics code, it
- # must be passed the -msse2 flag. However, with this flag, it may
- # emit SSE2 instructions even for scalar code, such as the CPUID
- # test used to test for the presence of SSE2. So that, and all other
- # code must be compiled *without* -msse2. The gyp lameness is that it
- # does not allow file-specific CFLAGS, so we must create this extra
- # target for those files to be compiled with -msse2.
- #
- # This is actually only a problem on 32-bit Linux (all Intel Macs have
- # SSE2, Linux x86_64 has SSE2 by definition, and MSC will happily emit
- # SSE2 from instrinsics, while generating plain ol' 386 for everything
- # else). However, to keep the .gyp file simple and avoid platform-specific
- # build breakage, we do this on all platforms.
-
- # For about the same reason, we need to compile the ARM opts files
- # separately as well.
