Image: Respect pixelStride when converting between image formats
...
Previously, this code assumed that a single channel image would always
have a pixel stride of 1. For image types where this assumption did not
hold, such as OpenGL, this function would produce incorrect results.

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.

Update code to use C++14 [[deprecated]] attribute
...
This commit removes the various compiler-specific JUCE_DEPRECATED macros and replaces them with C++14's deprecated attribute. It also removes the JUCE_CATCH_DEPRECATED_CODE_MISUSE flag as we can rely on the override specifier catching usage of these old virtual methods, and tidies up the DOXYGEN preprocessor checks as they were inconsistent across the codebase.
