Fixed the bug using uniform block array At the beginning of Program::defineUniformBlock, getUniformBlockSize will call getUniformBlockIndex on MacOS to check if the block is an active block with giving blockName. However, it didn't distinguish array and non-array situations and unified to use interfaceBlock.name as the blockName to call getUniformBlockIndex. It would result that INVALID_INDEX was returned when it's a block array. For example, using 'blockName' not 'blockName[0]'. In OpenGL 4.3 spec, section 7.3.1, there are following descriptions: If name exactly matches the name string of one of the active resources for programInterface, the index of the matched resource is returned. Additionally, if name would exactly match the name string of an active resource if "[0]" were appended to name, the index of the matched resource is returned. Otherwise, name is considered not to be the name of an active resource, and INVALID_INDEX is returned. So, for array block case, we use blockName appending [0] to check the activity.
