147 | If ROOTLESS_PROTECT_ALPHA is set, we have to make sure that the alpha | |
148 | channel of the on screen windows is always opaque. fb makes this harder | |
149 | than it would otherwise be by noticing that a planemask of 0x00ffffff | |
150 | includes all bits when depth==24, and so it "optimizes" the planemask to | |
151 | 0xffffffff. We work around this by temporarily setting depth=bpp while | |
152 | changing the GC. | |
153 | ||
154 | So the normal situation (in 32 bit mode) is that the planemask is | |
155 | 0x00ffffff and thus fb leaves the alpha channel alone. The rootless | |
156 | implementation is responsible for setting the alpha channel opaque | |
157 | initially. | |
158 | ||
159 | Unfortunately drawing with a planemask that doesn't have all bits set | |
160 | normally causes fb to fall off its fastest paths when blitting and | |
161 | filling. So we try to recognize when we can relax the planemask back to | |
162 | 0xffffffff, and do that for the duration of the drawing operation, | |
163 | setting the alpha channel in fg/bg pixels to opaque at the same time. We | |
164 | can do this when drawing op is GXcopy. We can also do this when copying | |
165 | from another window since its alpha channel must also be opaque. | |
166 | ||
167 | The three macros below are used to implement this. Drawing ops that can | |
168 | potentially have their planemask relaxed look like: | |
