OpenGLFrameBuffer: Add a row order parameter for reading and writing pixels
...
This also fixes a bug where saving and restoring the framebuffer state
could unexpectedly apply a vertical flip to the buffer content.

OpenGL: Return image BitmapData in JUCE order rather than native order
...
JUCE convention is that BitmapData holds the lines of the image ordered
from top to bottom, but OpenGL orders lines in the reverse direction.
By returning a negative line stride, we can iterate lines in the
expected order as long as we always increment the current pointer
position by the line stride after processing each line.

Image: Keep track of contiguous buffer size to avoid heap buffer overflows
...
In CoreGraphicsPixelData::createImage, image data was copied from a
BitmapData created from the Image passed into the function.
The BitmapData instance didn't keep track of the size of the buffer it
pointed to, so the buffer size was computed by multiplying the
BitmapData height by its line stride. However, if the BitmapData pointed
to a subsection of an image, the `data` pointer might be offset from
the allocated region, and `data + lineStride * height` would point past
the end of the allocated region. Trying to read/copy this range would
cause a heap buffer overflow at the end of the range.
This change adjusts BitmapData so that it keeps track of the size of the
allocated region. Taking a subsection of an image should subtract the
data pointer offset from the size of the allocated region.
