- * HwcComposer2D provides a way for gecko to render frames
- * using hwcomposer.h in the AOSP HAL.
- *
- * hwcomposer.h defines an interface for display composition
- * using dedicated hardware. This hardware is usually faster
- * or more power efficient than the GPU. However, in exchange
- * for better performance, generality has to be sacrificed:
- * no 3d transforms, no intermediate surfaces, no special shader effects,
- * and loss of other goodies depending on the platform.
- *
- * In general, when hwc is enabled gecko tries to compose
- * its frames using HwcComposer2D first. Then if HwcComposer2D is
- * unable to compose a frame then it falls back to compose it
- * using the GPU with OpenGL.
