object and pixel format conversions will be
performed as needed to store the data into the surface.
The buffer is assumed to be positioned to the location where the
first pixel data to be stored in the surface pixel at location
(x, y)
is located.
Pixel data for a row will be read from adjacent locations within
the buffer packed as tightly as possible for increasing X
coordinates.
Pixel data for adjacent rows will be read offset from each other
by the number of buffer data elements defined by
scanlineStride

This method performs an operation which is semantically equivalent to
(though likely much faster than) this pseudo-code:
for (int y = 0; y < h, y++) { for (int x = 0; x < w; x++) { setArgb(dstx + x, dsty + y, reader.getArgb(srcx + x, srcy + y)); } }
