* mesa: Don't try to clear a NULL renderbufferIan Romanick2011-06-071-0/+8
| | | | | | | | | | | | | | In an ES2 context (or if GL_ARB_ES2_compatibility) is supported, the framebuffer can be complete with some attachments be missing. In this case the _ColorDrawBuffers pointer will be NULL. Fixes the crash in piglit test fbo-missing-attachment-clear.

* swrast: anisotropic filtering extensionAndreas Faenger2011-05-183-0/+414
| | | | | | | | | Anisotropic filtering extension for swrast intended to be used by osmesa to create high quality renderings. Based on Higher Quality Elliptical Weighted Avarage Filter (EWA). A 2nd implementation using footprint assembly is also provided. Signed-off-by: Brian Paul <[email protected]>

* swrast: fix readpix clampingMarek Olšák2011-04-221-4/+4
| | | | | | | | | | | | | | | | | | Broken with e5c6a92a12b5cd7db205d72039f58d302b0be9d5. (ARB_color_buffer_float) Clamping should occur if type != float, otherwise the MSBs of the resulting pixels are killed off. For example, reading back LUMINANCE = R+G+B can be greater than 0xff, but the result is naturally masked by 0xff for UNSIGNED_BYTE, leading to bogus results. The following bug report seems to want clamping to occur if type == half_float too. Not sure what's correct.

* swrast: Don't try to adjust_colors for <8bpc when handling R16, RG1616.Eric Anholt2011-04-181-3/+3
| | | | | | | | | The GL_RED and GL_RG were tricking this code into executing, but it's totally unprepared for a 16-bit channel and just rescaled the values down to 0. We don't have anything with <8bit channels alongside >8bit channels, so disabling it should be safe. Reviewed-by: Brian Paul <[email protected]>
