Fix T82042: Crash when rendering huge images

Crash is related to the definition of the GL_MAX_TEXTURE_SIZE. OpenGL does not clearly
defined `GL_MAX_TEXTURE_SIZE` exactly means. Both on AMD and NVIDIA we have issues with
huge textures that they don't get created even if they are smaller. (See {D9530} for
research).

This patch will try to create the texture in a smaller size when the texture creation
failed.

Final implementation by: Cl�ment Foucault

We should create a solution that doesn't need downscaling. For this specific case ARB_sparse_texture might help to create cleaner code, but you still have to commit the whole image what introduces several draw calls. Other improvement is to optimize the scaling; current implementation isn't optimized for performance.
