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.

WM Draw Methods now has a new option Automatic (default). This will set the draw method to triple buffer or overlap depending on the configuration. Ideally I could get all cases working well with triple buffer but it's hard in practice. At the moment there are two cases that use overlap instead: * opensource ATI drives on linux * windows software renderer Also added a utility function to check GPU device/os/driver.

GPUShader: Manually validate sampler count This happens on NVidia GPUs, using more textures than the maximum allowed by the gl will NOT trigger a linking issue (maybe because of bindless texture implementation?). So in this case we manually count the number of samplers per shader stage and compare it against the GL limit. We discard the shader if the sampler count is too high. This shows the user something is wrong with the shader.

World textures displaying for viewport in BI. This patch supports "Image or Movie" and "Environment map" types of world texture for the viewport. It supports: - "View", "AngMap" and "Equirectangular" types of mapping. - Different types of texture blending (according to BI world render). - Same color blending as when it lacked textures (but render via glsl). {F207734} {F207735} Example: {F275180} Original author: @valentin_b4w Regards, Alexander (Blend4Web Team).

Clay-Engine (merge clay-engine) Initial work by Clément Foucault with contributions from Dalai Felinto (mainly per-collection engine settings logic, and depsgraph iterator placeholder). This makes Blender require OpenGL 3.3. Which means Intel graphic card and OSX will break. Disable CLAY_ENGINE in CMake in those cases. This is a prototype render engine intended to help the design of real render engines. This is mainly an engine with enphasis in matcap and ambient occlusion. Implemented Features -------------------- * Clay Render Engine, following the new API, to be used as reference for future engines * A more complete Matcap customization with more options * Per-Collection render engine settings * New Ground Truth AO - not enabled Missing Features ---------------- * Finish object edit mode - Fix shaders to use new matrix - Fix artifacts when edge does off screen - Fix depth issue - Selection sillhouette - Mesh wires - Use mesh normals (for higher quality matcap) - Non-Mesh objects drawing - Widget drawing - Performance issues * Finish mesh edit mode - Derived-Mesh-less edit mode API (mesh_rende.c) * General edit mode - Per-collection edit mode settings * General engines - Per-collection engine settings (they are their, but they still need to be flushed by depsgraph, and used by the drawing code)

Potential fix for T43987, ambient occlusion different between offscreen and on screen rendering. Aaaaah, the beauty of driver implementations of OpenGL! Turns out the problem here is that drivers calculate df/dy differently in some cases (probably because OpenGL counts y reverse to how the window system does, so drivers can get confused). Fixed this for the ATI case based on info we have so far, there's also the Intel case which will be handled separately (missing info on Intel's renderer string etc). Unfortunately we can't really fix this for the general case so we'll have to haldle cases as they come in our tracker and by adding silly string comparisons in our GPU initialization module <sigh>.

Fix T67951: Bone selection is broken on some Intel GPUs The problem is that the `glDrawArraysInstancedBaseInstance` is ignoring the last parameter.

This removes stretched texels and bottom hemisphere seams artifacts caused by the octahedral projection previously used. This introduce versioning code for the lightcache which will discard any lightcache version that is not compatible. Differential Revision: https://developer.blender.org/D7066

GPU: Fix Issue with recursive downsample and Intel HDXXX This is caused by a driver bug that prevent us from rendering to (or even binding) a texture mip level that is below GL_TEXTURE_MAX_LEVEL of the target texture. This is fine in most drivers (and legal AFAIK) but not on thoses Intels HDXXX + Windows. As a fix we just put GL_TEXTURE_MAX_LEVEL lower (which is illegal because it is undefined behaviour), but in practice it works ok and does not trigger any warnings or errors. This commit fixes most of the problems encountered on these GPUs (T56668).

GPU: Add workarounds for buggy glBlitFramebuffer function on macOS + Radeon When calling glBlitFramebuffer on most (if not all) mac that have a GPU from the Radeon Pro series, the data is not properly copied and only a subset of the pixels are correctly copied. This only happens when blitting the depth buffer if the depth buffer is GL_DEPTH24_STENCIL8. Changing the depth buffer format to GPU_DEPTH32F_STENCIL8 fixes the issue but only works if blitting the depth componnent. The stencil componnent still provoke issues when being copied.

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

Bicubic bump map filtering. This commit introduces bicubic bump map capabilities for the viewport for OpenGL 3.0+ capable GPUs. To use the functionality change the bump mapping method to "best quality" Previous "best quality" setting becomes "medium quality" now. For non OpenGL 3.0 GPUs this becomes the same as "medium quality" Also: * added tooltip descriptions to the bump method settings. * modified the shader to ommit extraneous matrix multiplications for matrices already provided by OpenGL.
