3 months agoFix an issue where temporary textures could be reused too early by a different thread.

Fix an issue where temporary textures could be reused too early by a different thread.

When an EffectChain is done rendering (ie., has submitted all of the GL
rendering commands that it needs to), it releases all of the temporary
textures it's used back to a common freelist.

However, if another thread needs a texture of the same size and format,
it could be picking it off of the freelist before the GPU has actually
completed rendering the first thread's command list, and start uploading
into it. This is undefined behavior in OpenGL, and can create garbled
output depending on timing and driver. (I've seen this on at least the
classic Intel Mesa driver.)

Fix by setting fences, so that getting a texture from the freelist
will have an explicit ordering versus the previous work. This increases the
size of ResourcePool::TextureFormat, but it is only ever used in a private
std::map. std::map is node-based (it has to, since the C++ standard requires
iterators to it to be stable), and thus, sizeof(TextureFormat) does not factor
into sizeof(ResourcePool), and thus, there is no ABI break. Verified by
checking on libstdc++.

Fix an issue where we'd add an unneeded bounce for mipmaps in some cases.

Specifically, if we didn't need to bounce for mipmaps, but bounced for
some other reason (e.g. resizing), we'd still propagate the mipmap
requirements. This could lead to yet another bounce earlier up the chain.
A typical case would be YCbCrInput -> GammaExpansionEffect -> ResizeEffect,
where we'd have a completely unneccessary bounce between the input and the
gamma expansion.
