move ui loop out of hw/pvr
vk: implement multi-rendering, delay swap. Load fb before render pass
fps counter now counts frames, not renders
vk: force ignoreTexAlpha for 565 texture in case the supporting texture
has an alpha channel (RTT). Fixes Alone in the Dark cinematic scenes.
pvr: better detection of frame swapping (FB_R_SOF/FB_W_SOF)
pvr: synchronous rendering now always waits for render in progress
(speed measurement not reliable, render skipped when multi-rendering)
vk: limit swap chain size to 2
Keep in-use imave and image views when the texture is updated.
Fix inside clipping (18 wheeler rear mirror)
Wait until the graphics queue is idle before changing shared buffers and
attachments.
Refactoring
stencil must be reset to zero if poly isn't shadowed -> fixes jet set
radio "see-through" shadows
take culling into account for modvols
oit: reduce per-pixel and per-poly mem usage
oit: framebuffers weren't resized when needed
oit: poly with depth write disabled weren't drawn (Soul calibur missing
water surface)
Fix glsl error when two-volume mode needs fog attachment
BufferData was always allocated in host visible mem, regardless of the
mem property argument.
NVidia gpus don't support blitting to 565 and 5551, which is needed for
mipmaps, so convert to 8888 instead.
Use optimal tiling for oit pointers image (linear not supported by
nvidia and probably slower anyway)
oit screen drawer uses multiple final attachments
Set non-oit depth attachment as transient and lazily allocate mem
