[OpenJDK 2D-Dev] [9] Review Request: 8061831 [OGL] "java.lang.InternalError: not implemented yet" during the blit of VI to VI in xor mode

[Sergey Bylokhov]

Hello.
Please review the fix for jdk9.
Our blits machinary in case of absent of direct/general blits will use 
the AnyBlit, which uses surface.getRaster method. This method is not 
implemented in OGL surfaces, so we must have some blit, which covers all 
possible combinations of source/destination/composite.

In the fix for JDK-7124347[1] the new OGLAnyCompositeBlit was added, and 
this new blit covers situation, when we cannot call getRaster on 
destination and must read it to the temporary buffer. But it does not 
take into account that the same problem exists for the source. If the 
source surface is OpenGLSurface and xor composite is used we should copy 
it to the temporary buffer also.

In this fix I added some parameters, which configure OGLAnyCompositeBlit 
for the case when some kind of ogl source is passed.
