neoGFX Cross-Platform GPU-Oriented C++ Application/Game Framework -- Coming Soon

Introduction

neoGFX is a cross-platform GPU-oriented C++ application/game framework. neoGFX is open source with its public repository hosted on GitHub. As of May 2018 version 1.0 of neoGFX is about 80% complete; on release of version 1.0 the intention is that neoGFX will be dual licensed (licensable with GPLv3 or a commercial licence).

Features (when version 1.0 released):

clean modern C++ design including full exception safety supporting various widget allocation patterns (stack, member variable or free store);
use of standard non-proprietary C++ data types including using standard string classes (UTF-8 encoding) and containers from the C++ standard library;
simple, easy to use multi-threaded event system (an improvement over traditional signals and slots);
no baggage: neoGFX primarily contains only the GUI and graphics related functionality needed for creating apps and games;
full library of widgets and layout managers specifiable in an RJSON (Relaxed JSON) derived declarative UI description language drag/drop editable using the included design tool, neoGFX Design Studio;
CSS3 style sheet support with support for custom skins;
scripting engine, neos, that will be able to support a wide range of scripting languages (on release: neoscript, JavaScript and Lua);
sub-pixel text rendering;
simple window style for specifying that a window is "nested" rather than being a separate native desktop window;
"text_edit" widget supports multiple fonts, text colours (with optional gradient effects), colour emojis and rendering text in columns;
GPU shader rendered CSS3 compliant gradients with optional gaussian smoothing;
MVC (model-view-controller) related classes supporting robust and fast app design;
optional MDI support utilizing "nested" windows;
2D (initially) game support: sprites and 2D physics;
flexible asset management: texture images (e.g PNGs) can be stored in .zip archives which can be optionally embedded inside the program binary accessible using simple URLs;
support for OpenGL, DirectX and Vulkan.

Initial design goals will be:

for the API to be as clean and easy to use as possible;
no reliance on macro-based code generation used by certain other GUI libraries;
to be as fast as possible (after all this is C++) with compiled binaries having as small a memory footprint as possible with no huge redistributables;
3rd party dependencies include: Boost, SDL, FreeType and HarfBuzz.

The plan is for v1.0 supported platforms to be Windows (desktop) and Linux (desktop) followed later with OS X, iOS and Android support.
