| /* SkTypes.h, the root of the public header files, does the following trick: |
| |
| #include "SkPreConfig.h" |
| #include "SkUserConfig.h" |
| #include "SkPostConfig.h" |
| |
| SkPreConfig.h runs first, and it is responsible for initializing certain |
| skia defines. |
| |
| SkPostConfig.h runs last, and its job is to just check that the final |
| defines are consistent (i.e. that we don't have mutually conflicting |
| defines). |
| |
| SkUserConfig.h (this file) runs in the middle. It gets to change or augment |
| the list of flags initially set in preconfig, and then postconfig checks |
| that everything still makes sense. |
| |
| Below are optional defines that add, subtract, or change default behavior |
| in Skia. Your port can locally edit this file to enable/disable flags as |
| you choose, or these can be delared on your command line (i.e. -Dfoo). |
| |
| By default, this include file will always default to having all of the flags |
| commented out, so including it will have no effect. |
