2020-09-22	Fix T81026: Image Editor: Alpha (like Bloom) not showing properly	Jeroen Bakker
	With the new image editor drawing there were was some mutual exclusive functionality. When rendering the alpha was shown correctly or the pure emissive colors were shown correctly, but never both. The cause of this is that the image_gpu did not used the correct alpha mode when generating gpu textures for non-images (render results, compositors viewer) The implementation always checked the alpha_mode. Alpha mode is an attribute for images, but aren't set for non images. This patch adds a more detailed check to ensure that the gpu texture is premultiplied. The issue has been tested using several bug report files and production files. Reviewed By: Brecht van Lommel Differential Revision: https://developer.blender.org/D8978
2020-09-15	Fix T80776: Cannot switch between Slots of Render Result	Jeroen Bakker
	Introduced by D8234. Added active render slot to determine if the GPUTexture is still up to date.
2020-09-14	Fix T80705: Single Image Texture Painting Crash	Jeroen Bakker
	Regression introduced by {D8234}; GPU textures can be requested without an image user.
2020-09-11	Use DrawManager for Image/UV Editor	Jeroen Bakker
	This project moves the current UV/Image editor drawing to the draw manager. Why would we do this: Performance: Current implementation would draw each texel per time. Multiple texels could be drawn per pixel what would overwrite the previous result. You can notice this when working with large textures. Repeat image drawing made this visible by drawing for a small period of time and stop drawing the rest. Now the rendering is fast and all repeated images are drawn. Alpha drawing: Current implementation would draw directly in display space. Giving incorrect results when displaying alpha transparent images. This addresses {T52680}, {T74709}, {T79518} The image editor now can show emission only colors. See {D8234} for examples. Current Limitations Using images that are larger than supported by your GPU are resized (eg larger than 16000x16000 are resized to 8k). This leaves some blurring artifacts. It is a low priority to add support back of displaying individual pixels of huge images. There is a design task {T80113} with more detail. Implementation overview Introduced an Image Engine in the draw module. this engine is responsible for drawing the texture in the main area of the UV/Image editor. The overlay engine has a edit_uv overlay which is responsible to draw the UV's, shadows and overlays specifically for the UV Image editor. The background + checker pattern is drawn by the overlay_background. The patch will allow us to share overlays between the 3d viewport and UV/Image editor more easily. In most cases we just need to switch the `pos` with the `u` attribute in the vertex shader. The project can be activated in the user preferences as experimental features. In a later commit this will be reversed. Reviewed By: Clément Foucault Differential Revision: https://developer.blender.org/D8234
2020-09-08	Fix T79538 Grease Pencil: Fill texture doesn't tile anymore	Clément Foucault
	This was caused by rBe749643793809248dfc6ffd078be04aec3eeab82 which removed the texture repeat from Image texture.
2020-09-07	GPU: Rename gpu_extensions to gpu_capabilities	Clément Foucault
	This makes more sense as this module has more to it than just GL extensions.
2020-09-05	Cleanup: GPUTexture: Move debug messages outside of creation function	Clément Foucault
	# Conflicts: # source/blender/gpu/intern/gpu_framebuffer.cc
2020-09-05	GPUTexture: Change texture creation API	Clément Foucault
	This is to modernize the API: - Add meaningful name to all textures (except DRW textures). - Remove unused err_out argument: only used for offscreen python. - Add mipmap count to creation functions for future changes. - Clarify the data usage in creation functions. This is a cleanup commit, there is no functional change. # Conflicts: # source/blender/gpu/GPU_texture.h
2020-09-05	GPUTexture: Remove bind to edit calls	Clément Foucault
	This is going to be unecessary after the GPU opengl texture backend refactor. For now add a save/restore mechanism to leave the state untouched. Also remove some calls where the caller would bind to particular binding point and set the shader uniform.
2020-08-08	Cleanup: use array syntax for sizeof with fixed values	Campbell Barton
	Also order sizeof(..) first to promote other values to size_t.
2020-08-05	Fix unreported crash in gpu_free_unused_buffers	Lukas Stockner
	As far as I can see, this problem was introduced with the gpu_free_unused_buffers() changes in rB97b597c. The code checks the returned pointer to stop looping, but the last iteration will return the last GPUTexture and set the queue to NULL, meaning that the next pop() will crash.

2020-07-30	IMB: Refactor util_gpu.c to not expose enum getters	Clément Foucault
	This was causing compiler error on MSVC and is not a good idea in general.
2020-07-30	Cleanup: spelling	Campbell Barton

2020-07-30	Cleanup: GPU: Remove GPU_draw.h and move fluid gpu function to DRW	Clément Foucault

2020-07-30	Cleanup: Split gpu_texture_image.c into BKE and IMB modules	Clément Foucault
	This is in order to disolve GPU_draw.h into more meaningful code blocks. All the Image related function are in `image_gpu.c`. All the MovieClip related function are in `movieclip.c`. The IMB module now has a connection with GPU. This is not strickly necessary and the code could be move to `image_gpu.c` if needed. The Image garbage collection is also ported to `image_gpu.c`.
