                                                 const EFBRectangle& srcRect, bool isIntensity, bool scaleByHalf)
{
	// Emulation methods:
	//
	// - EFB to RAM:
	//      Encodes the requested EFB data at its native resolution to the emulated RAM using shaders.
	//      Load() decodes the data from there again (using TextureDecoder) if the EFB copy is being used as a texture again.
	//      Advantage: CPU can read data from the EFB copy and we don't lose any important updates to the texture
	//      Disadvantage: Encoding+decoding steps often are redundant because only some games read or modify EFB copies before using them as textures.
	//
	// - EFB to texture:
	//      Copies the requested EFB data to a texture object in VRAM, performing any color conversion using shaders.
	//      Advantage: Works for many games, since in most cases EFB copies aren't read or modified at all before being used as a texture again.
	//                 Since we don't do any further encoding or decoding here, this method is much faster.
	//                 It also allows enhancing the visual quality by doing scaled EFB copies.
	//
	// - Hybrid EFB copies:
	//      1a) Whenever this function gets called, encode the requested EFB data to RAM (like EFB to RAM)
	//      1b) Set type to TCET_EC_DYNAMIC for all texture cache entries in the destination address range.
	//          If EFB copy caching is enabled, further checks will (try to) prevent redundant EFB copies.
	//      2) Check if a texture cache entry for the specified dstAddr already exists (i.e. if an EFB copy was triggered to that address before):
	//      2a) Entry doesn't exist:
	//          - Also copy the requested EFB data to a texture object in VRAM (like EFB to texture)
	//          - Create a texture cache entry for the target (type = TCET_EC_VRAM)
	//          - Store a hash of the encoded RAM data in the texcache entry.
	//      2b) Entry exists AND type is TCET_EC_VRAM:
	//          - Like case 2a, but reuse the old texcache entry instead of creating a new one.
	//      2c) Entry exists AND type is TCET_EC_DYNAMIC:
	//          - Only encode the texture to RAM (like EFB to RAM) and store a hash of the encoded data in the existing texcache entry.
	//          - Do NOT copy the requested EFB data to a VRAM object. Reason: the texture is dynamic, i.e. the CPU is modifying it. Storing a VRAM copy is useless, because we'd always end up deleting it and reloading the data from RAM anyway.
	//      3) If the EFB copy gets used as a texture, compare the source RAM hash with the hash you stored when encoding the EFB data to RAM.
	//      3a) If the two hashes match AND type is TCET_EC_VRAM, reuse the VRAM copy you created
	//      3b) If the two hashes differ AND type is TCET_EC_VRAM, screw your existing VRAM copy. Set type to TCET_EC_DYNAMIC.
	//          Redecode the source RAM data to a VRAM object. The entry basically behaves like a normal texture now.
	//      3c) If type is TCET_EC_DYNAMIC, treat the EFB copy like a normal texture.
	//      Advantage: Non-dynamic EFB copies can be visually enhanced like with EFB to texture.
	//                 Compatibility is as good as EFB to RAM.
	//      Disadvantage: Slower than EFB to texture and often even slower than EFB to RAM.
	//                    EFB copy cache depends on accurate texture hashing being enabled. However, with accurate hashing you end up being as slow as without a copy cache anyway.
	//
	// Disadvantage of all methods: Calling this function requires the GPU to perform a pipeline flush which stalls any further CPU processing.
	//
	// For historical reasons, Dolphin doesn't actually implement "pure" EFB to RAM emulation, but only EFB to texture and hybrid EFB copies.
