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.

Code Style: use "#pragma once" in source directory This replaces header include guards with `#pragma once`. A couple of include guards are not removed yet (e.g. `__RNA_TYPES_H__`), because they are used in other places. This patch has been generated by P1561 followed by `make format`.

int GPU_max_textures(void);
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.

int GPU_texture_size_with_limit(int res);
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).

bool GPU_mip_render_workaround(void);
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.

bool GPU_depth_blitting_workaround(void);
Fix T77346: GPU Workaround Always Render Using Main Context In Blender 2.90 EEVEE materials were refactored that introduced crashes on Intel GPUs on Windows. The crash happened in the `local_context_workaround` that temporary stored compiled materials in a binary form to reload it in the main GL context. It has been tested that the workaround isn't needed anymore for HD6xx GPUs, but it is still needed for HD4000. After several unsuccesfull fixes we came to the conclusion that we could not support the local context workaround and needed to come with a different workaround. The idea of this patch is that in these cases there is only a single context that is used for rendering. Threads that uses these contextes are guarded by a mutex and will block. Impact on User Level: * Due to main mutex lock the UI freezes when rendering or baking or feel less snappy Reviewed By: Clément Foucault, Brecht van Lommel Differential Revision: https://developer.blender.org/D8410

bool GPU_use_main_context_workaround(void);
Fix/workaround T62167: Random crash when displaying wireframes. Some old AMD drivers crash when a vbo with stride 1 is used a few times. I have not found a real solution to this problem. So the solution was to use a vbo with stride 4 (which in theory is less efficient and takes up more memory space).

Add debug option --debug-gpumem to show GPU memory used in status bar. Only used in ATIs and NVIDIAs. Used extensions are: https://www.opengl.org/registry/specs/ATI/meminfo.txt http://developer.download.nvidia.com/opengl/specs/ If you read the documentation, the numbers are not supposed to be exact and also depend on the time when the call is made. The numbers can also change quite quickly. It's only meant to give a rough measure of what is going on.
