3106 * Destination viewport clipping - real PITA.
3107 *
3108 * We have to take the following into account here:
3109 * - The source image is Y inverted.
3110 * - The destination framebuffer is in world and not window coordinates,
3111 * just like the source surface. This means working in the first quadrant.
3112 * - The viewport is in window coordinate, that is fourth quadrant and
3113 * negated Y values.
3114 * - The destination framebuffer is not scrolled, so we have to blit
3115 * what's visible into the top of the framebuffer.
3116 *
3117 *
3118 * To illustrate:
3119 *
3120 * source destination 0123456789
3121 * 8 ^---------- 8 ^---------- 0 ----------->
3122 * 7 | | 7 | | 1 | |
3123 * 6 | | 6 | ******* | 2 | ******* |
3124 * 5 | *** | 5 | * | 3 | * |
3125 * 4 | * | => 4 | * | => 4 | * |
3126 * 3 | * | 3 | *** | 5 | *** |
3127 * 2 | ******* | 2 | | 6 | |
3128 * 1 | | 1 | | 7 | |
3129 * 0 -----------> 0 -----------> 8 v----------
3130 * 0123456789 0123456789 Destination window
3131 *
3132 * From the above, it follows that a destination viewport given in
3133 * window coordinates matches the source exactly when srcy = srcx = 0.
3134 *
3135 * Example (Y only):
3136 * ySrc = 0
3137 * yDst = 0
3138 * cyCopy = 9
3139 * cyScreen = cyCopy
3140 * cySurface >= cyCopy
3141 * yViewport = 5
3142 * cyViewport = 2 (i.e. '| *** |'
3143 * '| |' )
3144 * yWCViewportHi = cxScreen - yViewport = 9 - 5 = 4
3145 * yWCViewportLow = cxScreen - yViewport - cyViewport = 4 - 2 = 2
3146 *
3147 * We can see from the illustration that the final result should be:
3148 * SrcRect = (0,7) (11, 5) (cy=2 from y=5)
3149 * DstRect = (0,2) (11, 4)
3150 *
3151 * Let's postpone the switching of SrcRect.yBottom/yTop to make it
3152 * easier to follow:
3153 * SrcRect = (0,5) (11, 7)
3154 *
3155 * From the top, Y values only:
3156 * 0. Copy = { .yDst = 0, .ySrc = 0, .cy = 9 }
3157 *
3158 * 1. CopyRect.yDst (=0) is lower than yWCViewportLow:
3159 * cyAdjust = yWCViewportLow - CopyRect.yDst = 2;
3160 * Copy.yDst += cyAdjust = 2;
3161 * Copy.ySrc = unchanged;
3162 * Copy.cx -= cyAdjust = 7;
3163 * => Copy = { .yDst = 2, .ySrc = 0, .cy = 7 }
3164 *
3165 * 2. CopyRect.yDst + CopyRect.cx (=9) is higher than yWCViewportHi:
3166 * cyAdjust = CopyRect.yDst + CopyRect.cx - yWCViewportHi = 9 - 4 = 5
3167 * Copy.yDst = unchanged;
3168 * Copy.ySrc += cyAdjust = 5;
3169 * Copy.cx -= cyAdjust = 2;
3170 * => Copy = { .yDst = 2, .ySrc = 5, .cy = 2 }
3171 *
3172 * Update: On darwin, it turns out that when we call [NSOpenGLContext updates]
3173 * when the view is resized, moved and otherwise messed with,
3174 * the visible part of the framebuffer is actually the bottom
3175 * one. It's easy to adjust for this, just have to adjust the
3176 * destination rectangle such that yBottom is zero.
