New JSON dump format

Unified across VMA and D3D12MA.
Updated Python script for visualization - now called GpuMemDumpVis.py.

 - Statistics: Obtain brief or detailed statistics about the amount of memory used, unused, number of allocated heaps, number of allocations etc. - globally and per memory heap type. Current memory usage and budget as reported by the system can also be queried.
 - Debug annotations: Associate custom `void* pPrivateData` and debug `LPCWSTR pName` with each allocation.
 - JSON dump: Obtain a string in JSON format with detailed map of internal state, including list of allocations, their string names, and gaps between them.
-- Convert this JSON dump into a picture to visualize your memory using attached Python script.
+- Convert this JSON dump into a picture to visualize your memory. See [tools/GpuMemDumpVis](tools/GpuMemDumpVis/README.md).
 - Virtual allocator - an API that exposes the core allocation algorithm to be used without allocating real GPU memory, to allocate your own stuff, e.g. sub-allocate pieces of one large buffer.

+# GpuMemDumpVis
+
+Vulkan/D3D12 Memory Allocator Dump Visualization. 
+It is an auxiliary tool that can visualize internal state of [Vulkan Memory Allocator](https://github.com/GPUOpen-LibrariesAndSDKs/VulkanMemoryAllocator) and
+[D3D12 Memory Allocator](https://github.com/GPUOpen-LibrariesAndSDKs/D3D12MemoryAllocator) libraries on a picture.
+It is a Python script that must be launched from command line with appropriate parameters.
+
+## Requirements
+
+- Python 3 installed
+- [Pillow](http://python-pillow.org/) - Python Imaging Library (Fork) installed
+
+## Usage
+
+```
+python GpuMemDumpVis.py -o OUTPUT_FILE INPUT_FILE
+```
+
+* `INPUT_FILE` - path to source file to be read, containing dump of internal state of the VMA/D3D12MA library in JSON format (encoding: UTF-8/UTF-16), generated using `vmaBuildStatsString()` and `D3D12MA::Allocator::BuildStatsString()` functions.
+* `OUTPUT_FILE` - path to destination file to be written that will contain generated image. Image format is automatically recognized based on file extension. List of supported formats can be found [here](http://pillow.readthedocs.io/en/latest/handbook/image-file-formats.html) and includes: BMP, GIF, JPEG, PNG, TGA.
+
+You can also use typical options:
+
+* `-h` - to see help on command line syntax
+* `-v` - to see program version number
+
+## Example output
+
+![Example output](README_files/ExampleOutput.png "Example output")
+
+## Legend
+
+* ![Free space](README_files/Legend_Bkg.png "Free space") Light gray without border - a space in Vulkan device memory block unused by any allocation.
+* ![Buffer 1](README_files/Legend_Buffer_1.png "Buffer 1") Buffer with usage containing INDIRECT_BUFFER, VERTEX_BUFFER, or INDEX_BUFFER.
+* ![Buffer 2](README_files/Legend_Buffer_2.png "Buffer 2") Buffer with usage containing STORAGE_BUFFER or STORAGE_TEXEL_BUFFER.
+* ![Buffer 3](README_files/Legend_Buffer_3.png "Buffer 3") Buffer with usage containing UNIFORM_BUFFER or UNIFORM_TEXEL_BUFFER.
+* ![Buffer 4](README_files/Legend_Buffer_4.png "Buffer 4") Other buffer.
+* ![Image 1](README_files/Legend_Image_1.png "Image 1") Image with OPTIMAL tiling and usage containing DEPTH_STENCIL_ATTACHMENT or 1D/2D/3D texture with usage containing D3D12_RESOURCE_FLAG_ALLOW_DEPTH_STENCIL.
+* ![Image 2](README_files/Legend_Image_2.png "Image 2") Image with OPTIMAL tiling and usage containing INPUT_ATTACHMENT, TRANSIENT_ATTACHMENT or COLOR_ATTACHMENT, or 1D/2D/3D texture with usage containing D3D12_RESOURCE_FLAG_ALLOW_RENDER_TARGET or D3D12_RESOURCE_FLAG_ALLOW_UNORDERED_ACCESS.
+* ![Image 3](README_files/Legend_Image_3.png "Image 3") Image with OPTIMAL tiling and usage containing SAMPLED or 1D/2D/3D texture with usage not containing D3D12_RESOURCE_FLAG_DENY_SHARED_RESOURCE.
+* ![Image 4](README_files/Legend_Image_4.png "Image 4") Other image with OPTIMAL tiling or 1D/2D/3D texture.
+* ![Image Linear](README_files/Legend_Image_Linear.png "Image Linear") Image with LINEAR tiling.
+* ![Image Unknown](README_files/Legend_Image_Unknown.png "Image Unknown") Image with tiling unknown to the allocator.
+* ![Unknown](README_files/Legend_Unknown.png "Unknown") Allocation of unknown type.
+* ![Details](README_files/Legend_Details.png "Details") Black bar - one or more allocations of any kind too small to be visualized as filled rectangles.
