* Fix unnitialized memory in Sk2DPathEffect. The SkDescriptor checksumGravatar senorblanco@chromium.org2011-05-20
| | | | | | | | | | | | | | calculation for Sk2DPathEffect currently evaluates all the bytes in the embedded SkMatrix. This includes the type mask, which contains some uninitialized padding. Changing it to use SkMatrix::flatten() and SkMatrix::unflatten() (as SkGroupShape was doing) avoids the uninitialized data errors.

* The plain Makefile was using -Wall, but the gyp build wasn't. This CL turns onGravatar senorblanco@chromium.org2011-05-19
| | | | | | | | | | | | | | | | | | | -Wall -Wextra and -Wno-unused in common.gypi. This revealed a lot of warnings (and some actual bugs), all of which I fixed here. This is pretty mindless stuff for the most part (order of intialization, missing initializers, && within ||, etc), but will allow us to build cleanly with -Wall and -Wextra (and -Werror, if we so choose). I put defaults into switches that were missing cases. I could put in the actual missing enums instead if that's desired. I could also assert on missing enums instead of break, if that's desired. I wasn't sure how to test the stuff in "animator", so that should be looked at a bit more closely.

* [PDF] Add support for SrcIn, SrcOut, DstIn, DstOut xfermodes.Gravatar vandebo@chromium.org2011-05-13
| | | | | | | | | | This change uses the soft mask (aka soft clip) functionality of PDF to implement the xfermodes. It has to put existing content (dst) into a form xobject as well as putting the new (src) content into a different form xobject. It then draws one of them with the other as the soft mask. To accomplish this, we add a call to finishContentEntry after each call to setUpContentEntry - this is kind of a hack, but I don't see a better way to extract src. Unfortunately, soft mask is specified in the Graphic State PDF object (and not in the form xobject), so when handling one of these modes, we add a one time GS object to set the soft mask and invoke a simple GS to reset the soft mask when done.

* Edge antialiasing for convex shapes in GaneshGravatar senorblanco@chromium.org2011-05-12
| | | | | | | | | | | | | | | | | | | This patch implements edge antialiasing for convex shapes, using the fragment shader to compare against the edge equations for each triangle. Currently, it only works for flat shaded primitives (i.e., it was not integrated into the "active stages" path). The skia.gyp changes cause this code to be compiled into SampleApp, but do not enable the tesselated path by default. Notes: the SkOSWindow_Unix.cpp change is to silence a valgrind warning about memcpy() with overlapping regions. The GrBinHashKey change is to avoid running a two-pass hash (GrProgramDesc is now 52 bytes or so, exceeding the 32 byte default size).

* fix bug where we wrote uninitialized data to the flatten stream for shaders.Gravatar reed@google.com2011-05-10
| | | | | | | | | | | | | | | | | | | Both shader and gradient_shader write matrices to the flatten stream. However, they were just calling write(&matrix, sizeof(SkMatrix)) and the matrix can contain lazily-computed function ptrs as part of its internal cache. Thus two matrices that are logically the same may write different bytes. This is a problem because picture relies on flattening objects and then using the flatten stream as a key into its cache. This matrix-write bug effectively kills the effectiveness of the cache for shaders. The fix is to write proper read/write functions for matrix (and region btw). These call through to the existing low-level flatten routines (which just write into a memory ptr). git-svn-id: http://skia.googlecode.com/svn/trunk@1290 2bbb7eff-a529-9590-31e7-b0007b416f81
