 * The following are optional defines that can be enabled at the compiler
 * command line, in a IDE project, in a GrUserConfig.h file, or in a GL custom
 * file (if one is in use). If a GR_GL_CUSTOM_SETUP_HEADER is used they can
 * also be placed there.
 *
 * GR_GL_LOG_CALLS: if 1 Gr can print every GL call using SkDebugf. Defaults to
 * 0. Logging can be enabled and disabled at runtime using a debugger via to
 * global gLogCallsGL. The initial value of gLogCallsGL is controlled by
 * GR_GL_LOG_CALLS_START.
 *
 * GR_GL_LOG_CALLS_START: controls the initial value of gLogCallsGL when
 * GR_GL_LOG_CALLS is 1. Defaults to 0.
 *
 * GR_GL_CHECK_ERROR: if enabled Gr can do a glGetError() after every GL call.
 * Defaults to 1 if SK_DEBUG is set, otherwise 0. When GR_GL_CHECK_ERROR is 1
 * this can be toggled in a debugger using the gCheckErrorGL global. The initial
 * value of gCheckErrorGL is controlled by by GR_GL_CHECK_ERROR_START.
 *
 * GR_GL_CHECK_ERROR_START: controls the initial value of gCheckErrorGL
 * when GR_GL_CHECK_ERROR is 1.  Defaults to 1.
