/*
* Hardware Composer stress test
*
* Performs a pseudo-random (prandom) sequence of operations to the
* Hardware Composer (HWC), for a specified number of passes or for
* a specified period of time. By default the period of time is FLT_MAX,
* so that the number of passes will take precedence.
*
* The passes are grouped together, where (pass / passesPerGroup) specifies
* which group a particular pass is in. This causes every passesPerGroup
* worth of sequential passes to be within the same group. Computationally
* intensive operations are performed just once at the beginning of a group
* of passes and then used by all the passes in that group. This is done
* so as to increase both the average and peak rate of graphic operations,
* by moving computationally intensive operations to the beginning of a group.
* In particular, at the start of each group of passes a set of
* graphic buffers are created, then used by the first and remaining
* passes of that group of passes.
*
* The per-group initialization of the graphic buffers is performed
* by a function called initFrames. This function creates an array
* of smart pointers to the graphic buffers, in the form of a vector
* of vectors. The array is accessed in row major order, so each
* row is a vector of smart pointers. All the pointers of a single
* row point to graphic buffers which use the same pixel format and
* have the same dimension, although it is likely that each one is
* filled with a different color. This is done so that after doing
* the first HWC prepare then set call, subsequent set calls can
* be made with each of the layer handles changed to a different
* graphic buffer within the same row. Since the graphic buffers
* in a particular row have the same pixel format and dimension,
* additional HWC set calls can be made, without having to perform
* an HWC prepare call.
*
* This test supports the following command-line options:
*
* -v Verbose
* -s num Starting pass
* -e num Ending pass
* -p num Execute the single pass specified by num
* -n num Number of set operations to perform after each prepare operation
* -t float Maximum time in seconds to execute the test
* -d float Delay in seconds performed after each set operation
* -D float Delay in seconds performed after the last pass is executed
*
* Typically the test is executed for a large range of passes. By default
* passes 0 through 99999 (100,000 passes) are executed. Although this test
* does not validate the generated image, at times it is useful to reexecute
* a particular pass and leave the displayed image on the screen for an
* extended period of time. This can be done either by setting the -s
* and -e options to the desired pass, along with a large value for -D.
* This can also be done via the -p option, again with a large value for
* the -D options.
*
* So far this test only contains code to create graphic buffers with
* a continuous solid color. Although this test is unable to validate the
* image produced, any image that contains other than rectangles of a solid
* color are incorrect. Note that the rectangles may use a transparent
* color and have a blending operation that causes the color in overlapping
* rectangles to be mixed. In such cases the overlapping portions may have
* a different color from the rest of the rectangle.
