If enabled, when you - * use an Ximage for the back buffer in double buffered mode, the "swap" - * operation will be faster. You must also link with -lXext. - * - * Byte swapping: If the Mesa host and the X display use a different - * byte order then there's some trickiness to be aware of when using - * XImages. The byte ordering used for the XImage is that of the X - * display, not the Mesa host. - * The color-to-pixel encoding for True/DirectColor must be done - * according to the display's visual red_mask, green_mask, and blue_mask. - * If XPutPixel is used to put a pixel into an XImage then XPutPixel will - * do byte swapping if needed. If one wants to directly "poke" the pixel - * into the XImage's buffer then the pixel must be byte swapped first. In - * Mesa, when byte swapping is needed we use the PF_TRUECOLOR pixel format - * and use XPutPixel everywhere except in the implementation of - * glClear(GL_COLOR_BUFFER_BIT). We want this function to be fast so - * instead of using XPutPixel we "poke" our values after byte-swapping - * the clear pixel value if needed. - * - */ - -#ifdef __CYGWIN__ -#undef WIN32 -#undef __WIN32__ -#endif - -#include "glxheader.h" -#include "GL/xmesa.h" -#include "xmesaP.h" -#include "context.h" -#include "extensions.h" -#include "framebuffer.h" -#include "glthread.h" -#include "imports.h" -#include "matrix.h" -#include "mtypes.h" -#include "macros.h" -#include "renderbuffer.h" -#include "texformat.h" -#include "texobj.h" -#include "texstore.h" -#include "swrast/swrast.h" -#include "swrast_setup/swrast_setup.h" -#include "array_cache/acache.h" -#include "tnl/tnl.h" -#include "tnl/t_context.h" -#include "tnl/t_pipeline.h" -#include "drivers/common/driverfuncs.h" - -#ifdef XFree86Server -#include <GL/glxtokens.h> -#endif - -/* - * Global X driver lock - */ -_glthread_Mutex _xmesa_lock; - - - -/* - * Lookup tables for HPCR pixel format: - */ -static short hpcr_rgbTbl[3][256] = { -{ - 16, 16, 17, 17, 18, 18, 19, 19, 20, 20, 21, 21, 22, 22, 23, 23, - 24, 24, 25, 25, 26, 26, 27, 27, 28, 28, 29, 29, 30, 30, 31, 31, - 32, 32, 33, 33, 34, 34, 35, 35, 36, 36, 37, 37, 38, 38, 39, 39, - 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, - 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, - 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, - 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, - 96, 97, 98, 99, 100, 101, 102, 103, 104, 105, 106, 107, 108, 109, 110, 111, -112, 113, 114, 115, 116, 117, 118, 119, 120, 121, 122, 123, 124, 125, 126, 127, -128, 129, 130, 131, 132, 133, 134, 135, 136, 137, 138, 139, 140, 141, 142, 143, -144, 145, 146, 147, 148, 149, 150, 151, 152, 153, 154, 155, 156, 157, 158, 159, -160, 161, 162, 163, 164, 165, 166, 167, 168, 169, 170, 171, 172, 173, 174, 175, -176, 177, 178, 179, 180, 181, 182, 183, 184, 185, 186, 187, 188, 189, 190, 191, -192, 193, 194, 195, 196, 197, 198, 199, 200, 201, 202, 203, 204, 205, 206, 207, -208, 209, 210, 211, 212, 213, 214, 215, 216, 217, 218, 219, 220, 221, 222, 223, -224, 225, 226, 227, 228, 229, 230, 231, 232, 233, 234, 235, 236, 237, 238, 239 -}, -{ - 16, 16, 17, 17, 18, 18, 19, 19, 20, 20, 21, 21, 22, 22, 23, 23, - 24, 24, 25, 25, 26, 26, 27, 27, 28, 28, 29, 29, 30, 30, 31, 31, - 32, 32, 33, 33, 34, 34, 35, 35, 36, 36, 37, 37, 38, 38, 39, 39, - 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, - 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, - 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, - 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, - 96, 97, 98, 99, 100, 101, 102, 103, 104, 105, 106, 107, 108, 109, 110, 111, -112, 113, 114, 115, 116, 117, 118, 119, 120, 121, 122, 123, 124, 125, 126, 127, -128, 129, 130, 131, 132, 133, 134, 135, 136, 137, 138, 139, 140, 141, 142, 143, -144, 145, 146, 147, 148, 149, 150, 151, 152, 153, 154, 155, 156, 157, 158, 159, -160, 161, 162, 163, 164, 165, 166, 167, 168, 169, 170, 171, 172, 173, 174, 175, -176, 177, 178, 179, 180, 181, 182, 183, 184, 185, 186, 187, 188, 189, 190, 191, -192, 193, 194, 195, 196, 197, 198, 199, 200, 201, 202, 203, 204, 205, 206, 207, -208, 209, 210, 211, 212, 213, 214, 215, 216, 217, 218, 219, 220, 221, 222, 223, -224, 225, 226, 227, 228, 229, 230, 231, 232, 233, 234, 235, 236, 237, 238, 239 -}, -{ - 32, 32, 33, 33, 34, 34, 35, 35, 36, 36, 37, 37, 38, 38, 39, 39, - 40, 40, 41, 41, 42, 42, 43, 43, 44, 44, 45, 45, 46, 46, 47, 47, - 48, 48, 49, 49, 50, 50, 51, 51, 52, 52, 53, 53, 54, 54, 55, 55, - 56, 56, 57, 57, 58, 58, 59, 59, 60, 60, 61, 61, 62, 62, 63, 63, - 64, 64, 65, 65, 66, 66, 67, 67, 68, 68, 69, 69, 70, 70, 71, 71, - 72, 72, 73, 73, 74, 74, 75, 75, 76, 76, 77, 77, 78, 78, 79, 79, - 80, 80, 81, 81, 82, 82, 83, 83, 84, 84, 85, 85, 86, 86, 87, 87, - 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, - 96, 97, 98, 99, 100, 101, 102, 103, 104, 105, 106, 107, 108, 109, 110, 111, -112, 113, 114, 115, 116, 117, 118, 119, 120, 121, 122, 123, 124, 125, 126, 127, -128, 129, 130, 131, 132, 133, 134, 135, 136, 137, 138, 139, 140, 141, 142, 143, -144, 145, 146, 147, 148, 149, 150, 151, 152, 153, 154, 155, 156, 157, 158, 159, -160, 161, 162, 163, 164, 165, 166, 167, 168, 169, 170, 171, 172, 173, 174, 175, -176, 177, 178, 179, 180, 181, 182, 183, 184, 185, 186, 187, 188, 189, 190, 191, -192, 193, 194, 195, 196, 197, 198, 199, 200, 201, 202, 203, 204, 205, 206, 207, -208, 209, 210, 211, 212, 213, 214, 215, 216, 217, 218, 219, 220, 221, 222, 223 -} -}; - - - -/**********************************************************************/ -/***** X Utility Functions *****/ -/**********************************************************************/ - - -/* - * Return the host's byte order as LSBFirst or MSBFirst ala X. - */ -#ifndef XFree86Server -static int host_byte_order( void ) -{ - int i = 1; - char *cptr = (char *) &i; - return (*cptr==1) ?
