(WIP) Vulkan plugin for GeeXLab

[JeGX]

I started the coding of this #Vulkan plugin...

After two days of struggle, I can now clear the framebuffer (what a joke!) 
We can create a renderer + render window on a particular GPU, and the scene resize is also managed.

Next step: pipeline object + SPIR-V programs.

More than two days to get the Hello World of graphics programming!

To get this RGB triangle, I had to code most of the important functionalities of the plugin: PSOs (pipeline state object),  SPIR-V shaders (as well as the tool to convert GLSL to SPIR-V), vertex and uniform buffers... and waste a lot of time with bugs!

It's cool to see this triangle, the starting point of all virtual worlds...

The plugin has some basic texture management. The following demo shows a simple textured quad:

Cool, the line width is back with Vulkan!

Line width: 4.0



Line width: 10.0

An array of 2D textures is a simple way to use many textures (all with same dim). Here, a 8-texture array and a single quad rendered 8 times:

A very cool feature available in the next update of GeeXLab: a built-in support of True Type Fonts (no plugin required as in the case of the ftgl plugin) that works with all versions of OpenGL (GL2 / GL3+) and, of course, Vulkan.

The Vulkan plugin now works on Linux too (tested on Linux Mint 17.3 + GeForce GTX 780 + R364.12). I can now release the first version of GeeXLab with Vulkan support...
