00f2419388 Additional GUI updates to GL example code
- switch Compute selection to pull-down menu
- add TBB controller to ptexViewer
- small cleanup in Hud

note: shading should also switch to a pull-down

a07ad19559 Fixed examples to run correctly on high DPI displays with GLFW 3
The example code now uses the new glfw*FramebufferSize methods
to determine the size of the windows's framebuffer for rendering
and glfw*WindowSize method for user interaction

Fixes #263

8918173fda Improve stringification of shaders & kernels in build.
- added a _stringify function to top CMakeLists
- switched all stringification tasks to use the macro
- all suffixes are now .gen.h instead of .inc (to help cmake track dependencies)

f7f2ca2581 Move uniform block definitions out of osd common shader into client shader.
Important notice: all client shader code must have following functions and compose them to osd intrinsic shaders (vertex/tessEval/tessControl)

mat4 OsdModelViewMatrix()
mat4 OsdProjectionMatrix()
mat4 OsdModelViewProjectionMatrix()
float OsdTessLevel()
int OsdGreogryQuadOffsetBase()
int OsdPrimitiveIdBase()

We probably should write a utility class for basic binding of them, to make client code simpler.

876cf3bc86 fix GLFW problems with ptexViewer and paintTest
GLFW 3.0.1 made the reshape callback explicit. Since we are using it to setup some framebuffers,
we need to call this function ourselves before starting the main-loop.

30ec963112 fix example code to work with GLFW 3.0
- fix FindGLFW.cmake to match the new locations

- fix all viewer & examples to build with 3.0, 3.0.1 and 3.0.2

Note : ptxViewer and paintTest do not work with 3.0.1 and 3.0.2 (yet)

21b9fbbb95 Moving some member variables of OsdGlDrawContext from public to protected
and adding the requisite accessors

Note : all our example code goes through the same boiler-plate texture
binding code - we might want to move it as a member function of the DrawContext.

e6e7c96a52 We need to leverage our per-patch ptex indexing scheme in the EvalLimit API.
- replace ptex indexing with the FarPtexCoord structure as a way to pass per-patch
  ptex data to the shaders.

  We are replacing a vector<int> arranged as :
  int[0] : ptex face index
  int[1] : (u,v) as 16 bits encoding the log2 coordinate of the top left corner

  Instead we are now using a struct arranged as :
  int[0] : ptex face index
  int[1] : is a bit-field containing u,v, rotation, depth and non-quad

  The u,v coordinates have been reduced to 10 bits instead of 16, which still
  gives us a lot of margin.

- Replace OsdVertexBufferDescriptor with something more adequate for general
  primvar representation (this name will probably eventually change...)

- Improve OsdPatchDescriptor
    - add a "loop" boolean (true if the patch is of loop type)
    - add a GetPatchSize() accessor

- OsdPatchArray :
    - remove some redundant elements (still more to do there)

- Fix all shader / examples / regressions & stuff to make this all work.

fixes #143

d026aca006 use std::string instead of char* for regression shapes definition,
to avoid MSVC's literal length limitation on some big shapes.

a4c43b0522 fix some GLFW 3.0 issues - since we are still in beta, the API is changing a bit
- the closeWindowFun callback changed prototype (now returns void)
- keyboard functions now require the window handle (and pass it to the callback)
