31/**
32 * The following are optional defines that can be enabled at the compiler
33 * command line, in a IDE project, in a GrUserConfig.h file, or in a GL custom
34 * file (if one is in use). If a GR_GL_CUSTOM_SETUP_HEADER is used they can
35 * also be placed there.
36 *
37 * GR_GL_LOG_CALLS: if 1 Gr can print every GL call using SkDebugf. Defaults to
38 * 0. Logging can be enabled and disabled at runtime using a debugger via to
39 * global gLogCallsGL. The initial value of gLogCallsGL is controlled by
40 * GR_GL_LOG_CALLS_START.
41 *
42 * GR_GL_LOG_CALLS_START: controls the initial value of gLogCallsGL when
43 * GR_GL_LOG_CALLS is 1. Defaults to 0.
44 *
45 * GR_GL_CHECK_ERROR: if enabled Gr can do a glGetError() after every GL call.
46 * Defaults to 1 if SK_DEBUG is set, otherwise 0. When GR_GL_CHECK_ERROR is 1
47 * this can be toggled in a debugger using the gCheckErrorGL global. The initial
48 * value of gCheckErrorGL is controlled by by GR_GL_CHECK_ERROR_START.
49 *
50 * GR_GL_CHECK_ERROR_START: controls the initial value of gCheckErrorGL
51 * when GR_GL_CHECK_ERROR is 1. Defaults to 1.
52 *
53 * GR_GL_CHECK_ALLOC_WITH_GET_ERROR: If set to 1 this will then glTexImage,
54 * glBufferData, glRenderbufferStorage, etc will be checked for errors. This
55 * amounts to ensuring the error is GL_NO_ERROR, calling the allocating
56 * function, and then checking that the error is still GL_NO_ERROR. When the
57 * value is 0 we will assume no error was generated without checking.
