MILESTONES
===========


loader	-----> mesh ----> allocator
creator --|			|---> allocator
					|---> allocator


1. RenderState
------------
RenderState fully functional with Renderbuffer, TransforFeedback and
BufferedTexture.
Debug output from RenderState to show its connections.


2. Primitive creation
------------------
Find a simple way to manage creation of Primitives, possibly including
centralization of all RenderState and resource creation.
Write creation code for
	cube
	sphere
	axis
	transform controller


3. Transform Controller
-----------------------


4. Demo: Shadows (PCSS/cascading?)
---------------------------------


5. Demo: Depth of field (framebuffer demo)
-----------------------------------------


6. Demo: Virtual Texturing
-------------------------


7. Mocap Loader/Animator
------------------------


8. Skeleton Loader/Animator
---------------------------


16/1
====


13-15/1
=======
RenderState transforFeedback system
RenderState OpenGL flags & vars system
Maya script for exporting .obj files for RT applications, splits vertices when
	there are multiple uv coords or normals per vertex.
Created town_quads.obj and town_triangeles.obj with above exporter and QTOWN
DemoShadowMapping added, not finished


5/1
====
Moved utility functions for Mem and Gem to their respective global files rather
that forcing them into a wrapper class.
New classes: FramebufferState, fully integrated
RenderState framebufffer object system
	renderState::setFramebuffer() etc


2-4/1
=====
Reworked RenderState class for full use of buffer objects
- A single RAM blob
- A single GPU blob (resident as a buffer)
- Multiple GPU bind points for the same buffer
	a buffer bound to framebuffer + bound as texture in the next frame
- load/save File <---> RAM blob
- upload/download RAM blob <---> OpenGL managed blob
- pack/unpack OpenGL managed blob <---> texture/framebuffer
new classes: VertexState, ProgramState, UniformState, TextureState
new classes: Tracker (used for state tracking)
Syntax highlighting for shaders


31/12
=====
Passthrough shaders for normal mesh with position, normal, texcoord


30/12
=====
Set up git with correct .gitignore
Set up release environment
Directory structure that works with NSIGHT and deployment

29/12
=====
Enable BMP R8 och RGB8 rendering
Enable PFM R32F and RGB32F rendering
Solve the mipmap + DXT mess (RenderState::declareTextureData() for solution)
Create GEM_THROW() macro to throw runtime_error and change all catch clauses
TextureLoader::createMipLevels()
renderState::undeclareDexture()


28/12
=====
renderState texture system
	renderState::setTexture()
	renderState::declareTextures()
	remderState::bindTextures()


27/12
=====
class TextureLoader
	TextureLoader::load()
	TextureLoader::loadBMP()
	TextureLoader::loadPFM()
	TextureLoader::loadDXT1()
	TextureLoader::create()
	TextureLoader::save()
	TextureLoader::saveBMP()
	TextureLoader::savePFM()


26/12
======
renderstage::setUniform system
renderState::declareUniforms()
remderState::bindUniforms()


25/12
======
Allocator data progress system
1. writes sets isChanged flag, reads unsets flag
PRO: Very simple to use, just check isChanged() to know if data was updated
CON: ANY read will reset flag, so you might not get isChanged()==true where you
	 expect it.
2. same as 1 but let the application choose to reset the flag
PRO: Simple to use
CON: Only allows a single place for progress check.
3. keep track of writeCount counter, increase in all writes
PRO: The application can keep track of progress at any point in the code
CON: Harder to use, each application needs to save external counter to compare
	 against.
4. same as 3 but with reset functions
PRO: The application can keep track of progress at any point in the code
	 Simple to use, no external variables required.
CON: One place of reset means you can't have multiple points where you check 
     progress.
Implemented #4

meshloader::save
meshloader::reload

GLOABL ERROR SYSTEM
bind vertex attributes (done generically, use layout specifier to access)
