Refactored some code eto make implmentinng shaderprograms easier for all stages neeeded in screen spaced rendering

WIP: refactored somee code to make maintainnability a bit easier + R32F for highere precision depth buffer annd shader program to reender R32f trexture as gray scale RGBA

Boundary WIP, kinda works but get small errors and fluid behaves a bit...

See merge request !1

Boundary now working, altough fluid is a bit stiff duee to pressure solving and border intneraction, can't find any solutions iin any papeers to this issuee

Boundary WIP, kinda works but get small errors and fluid behaves a bit stiffer, but still some waht acceeptable, need to implement boundary particlee normals and maybe get better result

MOved files not used by FludiSimulatorApp to deeprecated dir old_src, src dir now only inludes used files

Rewrite/reeefactored code to an application for eeasieer maintnance, next refactor cuda code as well

Siimulation rendeered to FBO and displayed in ImGUI window, ImGUI now wiith docking. Main fiile nnow very larege prob needs refractor

Changed from glut to glfw and compatible with ImGUI, (next implement parameter control for easy testing)

GL_depthmask=TRUE solved particles popping in and out, issuee was deepth mask not cuda coda. + simpleGUI from lab4 does not work Maybe try ImGUI but reequires more changes
