Merge of first part of changes from the apricot branch, especially the features that are needed to run the game. Compile tested with scons, make, but not cmake, that seems to have an issue not related to these changes. The changes include: * GLSL support in the viewport and game engine, enable in the game menu in textured draw mode. * Synced and merged part of the duplicated blender and gameengine/ gameplayer drawing code. * Further refactoring of game engine drawing code, especially mesh storage changed a lot. * Optimizations in game engine armatures to avoid recomputations. * A python function to get the framerate estimate in game. * An option take object color into account in materials. * An option to restrict shadow casters to a lamp's layers. * Increase from 10 to 18 texture slots for materials, lamps, word. An extra texture slot shows up once the last slot is used. * Memory limit for undo, not enabled by default yet because it needs the .B.blend to be changed. * Multiple undo for image painting. * An offset for dupligroups, so not all objects in a group have to be at the origin.

GPU: add mechanism for splitting up big gpu_shader_material.glsl file Compiling this big file for every Eevee material is bad for performance, and now that we are adding more nodes it gets worse. This patch adds a simple mechanism to split up that file, and use only the parts used by shader nodes. When a function is used by GPU_link, we detect which GLSL file it came from and use it in GLSL code generation automatically. Dependencies between GLSL files are manually specified, and function names must be unique across all GLSL files. Most of the actual splitting up will be done in later commits.

GPUPass: Refactor gpupass caching system to allow fast gpumaterial creation. This is part of the work needed to refactor the material parameters update.

GPU: add gpu python module with export_shader() function to export GLSL shader. shader = gpu.export_shader(scene,material) Returns the GLSL shader that blender generates to produce the visual effect of material in scene for the purpose of reusing the shader in an external engine. This function is meant to be used in a material exporter so that the GLSL shader can be exported entirely. The return value is a dictionary containing the shader source code and all associated data. The full documentation is under sphinx. Warning: there has been an API between the patch and this commit: uniform['lamp'] and uniform['image'] now return python reference to ID block instead of ID name as before. The X3D exporter that uses this function must be adapted.

OpenSubdiv: Commit of OpenSubdiv integration into Blender This commit contains all the remained parts needed for initial integration of OpenSubdiv into Blender's subdivision surface code. Includes both GPU and CPU backends which works in the following way: - When SubSurf modifier is the last in the modifiers stack then GPU pipeline of OpenSubdiv is used, making viewport performance as fast as possible. This also requires graphscard with GLSL 1.5 support. If this requirement is not met, then no GPU pipeline is used at all. - If SubSurf is not a last modifier or if DerivesMesh is being evaluated for rendering then CPU limit evaluation API from OpenSubdiv is used. This only replaces the legacy evaluation code from CCGSubSurf_legacy, but keeps CCG structures exactly the same as they used to be for ages now. This integration is fully covered with ifdef and not enabled by default because there are several TODOs to be solved first: - Face varying data interpolation is not really cleanly implemented for GPU in OpenSubdiv 3.0. It is also not implemented for limit evaluation API. This basically means we'll have really hard time supporting UVs. - Limit evaluation only works with adaptivly subdivided meshes so far, which basically means all the points of CCG are pushed to the limit. This gives different result from old code. - There are some serious optimizations possible on the topology refiner creation, which would speed up initial OpenSubdiv mesh creation. - There are some hardcoded asumptions in the GPU and DerivedMesh areas which could be generalized. That's something where Antony and Campbell can help, making it so the code is structured in a way which is reusable by all planned viewport projects. - There are also some workarounds in the dependency graph to make sure OpenGL buffers are only freed from the main thread. Those who'll be wanting to make experiments with this code should grab dev branch (NOT master) from https://github.com/Nazg-Gul/OpenSubdiv/tree/dev There are some patches applied in there which we're working on on getting into upstream.

GPUMaterial: Add Material shader cache. This is mostly to avoid re-compilation when using undo/redo operators. This also has the benefit to reuse the same GPUShader for multiple materials using the same nodetree configuration. The cache stores GPUPasses that already contains the shader code and a hash to test for matches. We use refcounts to know when a GPUPass is not used anymore. I had to move the GPUInput list from GPUPass to GPUMaterial because it's containing references to the material nodetree and cannot be reused. A garbage collection is hardcoded to run every 60 seconds to free every unused GPUPass.

Fix crash when editing shaders on Intel HD 4000. In the Intel HD 4000 driver a shader has to be deleted in the same context in which it is created. However, because you can't use a rendering context on different threads, to maintain the multithreaded compilation, the solution was to use the `GL_ARB_get_program_binary` and copy the binary generated for the shader and generate a shader on the main context using that binary. This solution is limited only to Intel HD 4000 and windows. Reviewers: fclem Reviewed By: fclem Differential Revision: https://developer.blender.org/D5019
