  Message : Return the correct location count for matrices in structs GetLocationCount() returned secondary size for fields of a struct. For matrices however, the correct value would be the primary size. This is a similar fix to 6423b7fc7ded02a702d24feb0730731ab9f6c061. Bug: angleproject:4200 Change-Id: I2c69b9454729993010766fcde0cabec986b7429d Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/2021738 Reviewed-by: Courtney Goeltzenleuchter <courtneygo@google.com> Reviewed-by: Tim Van Patten <timvp@google.com> Commit-Queue: Shahbaz Youssefi <syoussefi@chromium.org>
