Instead of rendering the swizzled result to the destination texture, render to another intermediate texture and then CopyTexImage it into the destination texture. Rendering to arbitrary mip levels of the destination texture is not always supported but CopyTexImage-ing is.

	53b8aec0	2015-08-24T10:33:25		Work around deprecated LUMA formats in the core profile. Use R and RG textures with swizzle states to emulate them. A manual blit is required when calling CopyTex[Sub]Image from a RGB[A] framebuffer to an emulated L[A] texture so that the alpha channel ends up in the correct channel of the destination texture. Fixes the following tests when using the core profile: * conformance/extensions/oes-texture-float.html * conformance/extensions/oes-texture-half-float.html * conformance/textures/misc/tex-sub-image-2d.html * conformance/textures/misc/texture-formats-test.html * conformance/textures/misc/texture-npot.html BUG=angleproject:1113 Change-Id: If5540e66d9017596bd83d95ec3ede043cbcfe0d2 Reviewed-on: https://chromium-review.googlesource.com/293905 Reviewed-by: Jamie Madill <jmadill@chromium.org> Tested-by: Geoff Lang <geofflang@chromium.org>
