2007-03-27fix incorrect _MaxElement calculationRoland Scheidegger
The calculation of _MaxElement was wrong if the stride was larger than elementSize, which lead to rejection of every DrawElements call which accessed the maximum element if CheckArrayBounds was enabled.
2007-03-27Restore the UseTexEnvProgram logic.Brian
Was removed during glsl-compiler work. Still need to go back and revisit this because of the interaction with fragment shaders...

2007-03-24Free shader-related context state: _mesa_free_shader_state()Brian
2007-03-23Implement alpha buffer copy for SwapBuffers().Brian
Nicolai writes: When the pixmap pixel format has no alpha channel, the x11 driver (software rendering) adds a wrapped alpha channel on request. During SwapBuffers, this alpha channel is not copied from back to front, which means that the front buffer doesn't really contain the contents that the back buffer previously contained. A subsequent glReadPixels from the front buffer will return an incorrect result. The following patch attempts to fix this.
2007-03-23Add the ability to generate programs that doesn't use condition codes.Brian
ctx->Shader.EmitCondCodes determines if we use condition codes. If not, IF statement uses first operand's X component as the condition. Added OPCODE_BRK0, OPCODE_BRK1, OPCODE_CONT0, OPCODE_CONT1 to handle the common cases of conditional break/continue.

if not bail accordingly. Previously we'd only do this test on compressed textures.

2007-03-16Assorted fixes for dealing with zero-size frame/renderbuffers.Brian
In xmesa_check_and_update_buffer_size() handle xmctx==NULL correctly: still call _mesa_resize_framebufer(). If we don't we can wind up in a situation where the framebuffer size is non-zero but an attached renderbuffer size is still initialized to zero. This inconsistancy can later cause problems. Check for zero-size renderbuffers in update_color_draw_buffers() and update_color_read_buffer(). See bug 7205.
2007-03-16Colortable re-org.Brian
The pixel transfer path has three color table lookups. Use an array [3] to store that info, rather than separate variables.

2007-03-14Re-org of gl_pixel_attrib struct.Brian
Reorder fields according to the order in which the pixel transfer operations take place. Improve comments. Move the pixel maps out of gl_pixel_attrib since they're not supposed to be pushed/popped by glPush/PopAttrib. New gl_pixelmap and gl_pixelmaps structs to contain the pixelmaps.

GL_MAX_DRAW_BUFFERS is currently 4. Added gl_FragData[] output for fragment programs. In _swrast_write_rgba_span() loop over the color outputs/renderbuffers.

2007-03-08 remove a if-statementXiang, Haihao
glMaterial changes the current specular exponent or glLight changes the intensity distribution of the light, but _mesa_update_state doesn't update the corresponding light table. So they must be updated at this time.

2007-03-06Fix/improve framebuffer object reference counting.Brian
Use _mesa_reference_framebuffer() and _mesa_unreference_framebuffer() functions to be sure reference counting is done correctly. Additional assertions are done too. Note _mesa_dereference_framebuffer() renamed to "unreference" as that's more accurate.
