3107 * Destination viewport clipping - real PITA.
3108 *
3109 * We have to take the following into account here:
3110 * - The source image is Y inverted.
3111 * - The destination framebuffer is in world and not window coordinates,
3112 * just like the source surface. This means working in the first quadrant.
3113 * - The viewport is in window coordinate, that is fourth quadrant and
3114 * negated Y values.
3115 * - The destination framebuffer is not scrolled, so we have to blit
3116 * what's visible into the top of the framebuffer.
3117 *
3118 *
3119 * To illustrate:
3120 *
3121 * source destination 0123456789
3122 * 8 ^---------- 8 ^---------- 0 ----------->
3123 * 7 | | 7 | | 1 | |
3124 * 6 | | 6 | ******* | 2 | ******* |
3125 * 5 | *** | 5 | * | 3 | * |
3126 * 4 | * | => 4 | * | => 4 | * |
3127 * 3 | * | 3 | *** | 5 | *** |
3128 * 2 | ******* | 2 | | 6 | |
3129 * 1 | | 1 | | 7 | |
3130 * 0 -----------> 0 -----------> 8 v----------
3131 * 0123456789 0123456789 Destination window
3132 *
3133 * From the above, it follows that a destination viewport given in
3134 * window coordinates matches the source exactly when srcy = srcx = 0.
3135 *
3136 * Example (Y only):
3137 * ySrc = 0
3138 * yDst = 0
3139 * cyCopy = 9
3140 * cyScreen = cyCopy
3141 * cySurface >= cyCopy
3142 * yViewport = 5
3143 * cyViewport = 2 (i.e. '| *** |'
3144 * '| |' )
3145 * yWCViewportHi = cxScreen - yViewport = 9 - 5 = 4
3146 * yWCViewportLow = cxScreen - yViewport - cyViewport = 4 - 2 = 2
3147 *
3148 * We can see from the illustration that the final result should be:
3149 * SrcRect = (0,7) (11, 5) (cy=2 from y=5)
3150 * DstRect = (0,2) (11, 4)
3151 *
3152 * Let's postpone the switching of SrcRect.yBottom/yTop to make it
3153 * easier to follow:
3154 * SrcRect = (0,5) (11, 7)
3155 *
3156 * From the top, Y values only:
3157 * 0. Copy = { .yDst = 0, .ySrc = 0, .cy = 9 }
3158 *
3159 * 1. CopyRect.yDst (=0) is lower than yWCViewportLow:
3160 * cyAdjust = yWCViewportLow - CopyRect.yDst = 2;
3161 * Copy.yDst += cyAdjust = 2;
3162 * Copy.ySrc = unchanged;
3163 * Copy.cx -= cyAdjust = 7;
3164 * => Copy = { .yDst = 2, .ySrc = 0, .cy = 7 }
3165 *
3166 * 2. CopyRect.yDst + CopyRect.cx (=9) is higher than yWCViewportHi:
3167 * cyAdjust = CopyRect.yDst + CopyRect.cx - yWCViewportHi = 9 - 4 = 5
3168 * Copy.yDst = unchanged;
3169 * Copy.ySrc += cyAdjust = 5;
3170 * Copy.cx -= cyAdjust = 2;
3171 * => Copy = { .yDst = 2, .ySrc = 5, .cy = 2 }
3172 *
3173 * Update: On darwin, it turns out that when we call [NSOpenGLContext updates]
3174 * when the view is resized, moved and otherwise messed with,
3175 * the visible part of the framebuffer is actually the bottom
3176 * one. It's easy to adjust for this, just have to adjust the
3177 * destination rectangle such that yBottom is zero.
