viewer#2741 Don't reallocate image conversion buffer all the time

2024-10-20T13:48:27Z

Do deprecated texture swizzle on GPU using GL texture swizzling functions (#2389)

2024-08-22T15:25:25Z

* Use GL texture swizzling instead of scratch buffer for deprecated formats when GL 3.3 is available Fix crash when GL texture compression is enabled * Fix UI font atlas being eligible for texture compression

Improve accuracy of texture memory tracking (#2371)

2024-08-21T14:47:31Z

* Fix alloc_tex_image to account for more missing texture memory Change alloc_tex_image calls to pass internal format to properly account for used image type * Fix scaleDown passing primary format in place of internal format to glTexImage2D * Make texture debug view and texture bias calculation consistent and remove double accounting for render target textures

#1870 Tune up for better experience on integrated intel with low memory (#1872)

2024-07-03T22:42:24Z

* More deterministic vsize calculation. Add control for choosing downscale method. * Quick hack to make GLTF preview work again

1836 dont store texture in system memory unless absolutely necessary (#1843)

2024-06-27T18:12:43Z

* #1836 Texture memory usage overhaul. Much decrufting - don't keep a copy of textures in system memory - use GPU to downrez textures instead of reloading from cache - use GPU to generate brightness/darkness bumpmaps
