示例1:

// optimization, i.e.:
// SAVE_LAYER
// DRAW_BITMAP|DRAW_BITMAP_MATRIX|DRAW_BITMAP_NINE|DRAW_BITMAP_RECT_TO_RECT
// RESTORE
//
// saveLayerHasPaint - control if the saveLayer has a paint (the optimization
// takes a different path if this is false)
// dbmr2rHasPaint - control if the dbmr2r has a paint (the optimization
// takes a different path if this is false)
// colorsMatch - control if the saveLayer and dbmr2r paint colors
// match (the optimization will fail if they do not)
