From 18a285a5e244b7405b85feb7315a30d99920ec5d Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Sat, 16 Mar 2002 00:53:15 +0000 Subject: Lots of changes related to framebuffer/window buffer resizing. Basically, instead of passing a GLcontext* to ResizeBuffers(), pass a GLframebuffer*. The idea is that a window can be resized without it being bound to a rendering context. This makes for a nice clean-up in the XFree86 server-side GLX code. Renamed ctx->Driver.ResizeBuffersMESA() to ctx->Driver.ResizeBuffers(). --- src/mesa/drivers/dos/dmesa.c | 9 +++- src/mesa/drivers/glide/fxdd.c | 25 +++++---- src/mesa/drivers/osmesa/osmesa.c | 16 +++--- src/mesa/drivers/svga/svgamesa.c | 5 +- src/mesa/drivers/windows/wmesa.c | 9 ++-- src/mesa/drivers/x11/xm_api.c | 17 ++++-- src/mesa/drivers/x11/xm_dd.c | 113 ++++++++++++++++++++------------------- src/mesa/drivers/x11/xmesaP.h | 6 ++- src/mesa/main/buffers.c | 56 +++++++++++++------ src/mesa/main/context.c | 5 +- src/mesa/main/mtypes.h | 4 +- src/mesa/swrast/s_accum.c | 36 ++++++------- src/mesa/swrast/s_accum.h | 9 ++-- src/mesa/swrast/s_alphabuf.c | 103 +++++++++++++++-------------------- src/mesa/swrast/s_alphabuf.h | 8 +-- src/mesa/swrast/s_buffers.c | 20 +++---- src/mesa/swrast/s_depth.c | 41 +++++++------- src/mesa/swrast/s_depth.h | 6 +-- src/mesa/swrast/s_stencil.c | 20 ++++--- src/mesa/swrast/s_stencil.h | 4 +- src/mesa/swrast/swrast.h | 9 ++-- 21 files changed, 281 insertions(+), 240 deletions(-) (limited to 'src/mesa') diff --git a/src/mesa/drivers/dos/dmesa.c b/src/mesa/drivers/dos/dmesa.c index 454b891c08..d150cdca5a 100644 --- a/src/mesa/drivers/dos/dmesa.c +++ b/src/mesa/drivers/dos/dmesa.c @@ -540,8 +540,13 @@ static GLboolean set_draw_buffer (GLcontext *ctx, GLenum mode) * If anything special has to been done when the buffer/window is * resized, do it now. */ -static void get_buffer_size (GLcontext *ctx, GLuint *width, GLuint *height) +static void get_buffer_size (GLframebuffer *buffer, GLuint *width, GLuint *height) { + /* XXX this may not be right.
