| 10 | |
| 11 The gles2/ subdirectory defines the GLES2 C API that's available to Mojo | |
| 12 applications. To use GLES2, Mojo applications must link against a dynamic | |
| 13 library (the exact mechanism being platform-dependent) and use the header files | |
| 14 in this directory as well as the standard Khronos GLES2 header files. | |
| 15 | |
| 16 The reason for this, rather than providing GLES2 using the standard Mojo IPC | |
| 17 mechanism, is performance: The protocol (and transport mechanisms) used to | |
| 18 communicate with the Mojo GLES2 service is not stable nor "public" (mainly for | |
| 19 performance reasons), and using the dynamic library shields the application from | |
| 20 changes to the underlying system. | |
